Why Is There Blood in My Cervical Mucus?



Your cervical mucus, also known as cervical fluid, is an important part of conception. It normally shows up just before ovulation and in some instances it can also be used to chart your most fertile time. If you are seeing blood in the mix, it is most likely due to common non-threatening sources. The main reasons you may see blood are implantation of a fertilized egg, the breach that happens as your egg is released you’re your ovaries, and even trauma to the cervix due to intercourse.

What is Cervical Mucus?

Fertile cervical mucus is a clear, slick, and moist fluid produced by a woman’s body to help a man’s sperm to reach their destination. In addition to leading the sperm to your cervix, this substance also helps to protect healthy sperm and filter out the unhealthy little swimmers. In other words, the cervical fluid plays a key role in helping a woman to conceive a child.

As your body changes in preparation for ovulation and conception the fluid will change as well. You may notice that your cervical mucus starts out as clear and thick before thinning out and eventually drying up as you near the end of ovulation. In some instances, women will not produce the substance outside of the body. You can still check for the presence of your cervical fluid by using your fingers to collect a small amount from your cervix.

Common Reasons For Blood in Your Cervical Mucus

The moment you notice blood in your cervical fluid, is not the time to panic. The spotting you see in your mucus is usually from several common occurrences. Light bleeding or a pink-ish colored cervical fluid can also be a good sign if you are trying to conceive. Implantation of a fertilized egg is one of the causes of blood in the cervical mucus. This bleeding occurs when the egg implants itself in your uterine wall and will last up to 2 days. Unfortunately this does not happen for every woman.

One of the most common reasons for the presence of a pink tint in your fluid is the shedding of old blood from your previous menstrual cycle. As you finish your period, there may be a small amount of blood trapped in the cervix. When you begin ovulation, this blood will mix with your cervical mucus and cause the spotting of blood.

Other reasons for seeing blood in your cervical mucus include ovulation and trauma to the cervix. When ovulation begins, many women may notice the presence of blood. As your egg leaves the ovaries, it may cause a small rupture in the ovarian follicle and result in the appearance of a small amount of blood. This is quite common and there is no need for you to worry. Blood in your cervical mucus is also commonly caused by trauma to your cervix. It really isn’t as dramatic as it sounds. Trauma could be anything from intercourse to a small scratch from your nails when checking for cervical fluid.

The many causes of blood in your cervical mucus ensure that most often the occurrence is nothing to worry about. A light spotting on or around the time of your ovulation can actually be a very good sign and in some cases may indicate that you are carrying new life. If you find that the bleeding gets heavier or will not cease, you should contact your doctor as soon as possible. Only a physician can rule out negative causes for any heavy non-period bleeding.

  • mrscolts

    i was 1 day late then i had had brown stuff come out of me then i started spotting then started bleeding heavy for 3 days now it stopped why

  • earthsmagic

    It just sounds like your period to me. A day late isn’t really a big deal. There are a lot of things that can cause a delay like stress, your weight, increased exercise, starting or stopping new medications, birth control, and medical issues like PCOS.

    i had my period this june 12-16,on june 19 i had unprotective sex with my husband.after 2 days i had this spotting and when i wipe it it had a little streak of blood. is this ovulation? we also had sex the day after that brownish spotting.i have a irregular period so i dont know exactly when im going to have ovulate/menstruation. it is like 26 27 or 28 cycle.

    Ovulation typically is 14 days from the day you start your period. The 19 and 20th would have been too early. It could be that the blood that you saw was actually left over from your period. Our ovulation calendar shows the following for your fertile time, based on a 27 day cycle:

    Friday 21st June 2013 – A little bit fertile
    Saturday 22nd June 2013 – Fertile
    Sunday 23rd June 2013 – VERY fertile
    Monday 24th June 2013 – Time to ovulate

  • Mamma11

    I was 11 days late for my period the day before I got it I spotted a little bit in the morning the next day my period started but very light it was off and on stopping and starting 8 days later I’ve started bleeding again with watery red blood through stringy mucus I’m confused

  • http://www.babyhopes.com/ Vickie B.

    Unfortunately, you may want to contact your doctor to find out what could be going on as this is not a typical bleeding pattern.

  • jlove

    i was suppose to have had my period on july 13th but i just started today it is bright red stringy mucus type stuff should i take a home test?

  • mdj

    I have a 28 day cycle I started my period on july 3 and ended july 10 on july 20th I had pink mucus spotting only when I wiped less than a day, is this implantation spotting or ovulation spotting?

  • http://www.babyhopes.com/ Vickie B.

    Based on our ovulation calendar, and the assumption you have the average 28 day cycle:

    Wednesday 3rd July 2013 – First day of your cycle
    Saturday 13th July 2013 – A little bit fertile
    Sunday 14th July 2013 – Fertile
    Monday 15th July 2013 – VERY fertile
    Tuesday 16th July 2013 – Time to ovulate

    Based on these dates, it is hard to say what the cause was. Implantation bleeding typically happens about 6 days after ovulation. If you have a cycle that is longer than 28 days, it could be ovulation spotting.

    I have a very regular period normally start at the end of every month. I am supposed to get my period on the 29th of this month but onn the 20 I had streaks of blood in my cervical mucus. it was only three times when I wiped, and it has stopped since then I have had mild cramping now and then. Is this normal? Should I test for pregnancy?
    Thank you, Vicki w.

  • http://www.babyhopes.com/ Vickie B.

    If you had sex around ovulation, that could have been implantation bleeding. Any pregnancy test you use now should show if you are pregnant.

  • http://www.babyhopes.com/ Vickie B.

    Have you taken a pregnancy test? If you got pregnant in June, a pregnancy test would definitely show by now. Based on what you are saying though, if you are pregnant, it would most likely be from sex this month.

    The ovulation calendar shows the following:

    Friday 12th July 2013 – A little bit fertile
    Saturday 13th July 2013 – Fertile
    Sunday 14th July 2013 – VERY fertile
    Monday 15th July 2013 – Time to ovulate

    If you had sex any of these days without protection, there is a chance that your symptoms could be caused by being pregnant.

  • Jesa

    My period was a day late and then only lasted a day. That was July 11. Now I am having cramping and had some mucus with a little blood in it. Could this mean anything?

  • yohana

  • Wondering

  • peng

    i had my mens august 21-25 last month, and supposed to get it last september 21 but still none until now.. i had a dark brown stinged cervical mucus yesterday and today and even on the 2nd wk or 3rd wk this month (i cannot remember the exact days, and it was for 3-4 days).. we had coitus last september 3 and september 11 or 12 (i am not sure with the date), he came inside me but with condom all through the deed.. i took 3 home urine PTs and were all negatives. i have not gone to any clinic yet.. im so worried to what caused my delayed menstruation and the dark brown stinged cervical mucus? my cousin has PCOS, im worried about that too.. i also had weight loss.. this is not the first time that i experienced this kind of delay, i also experienced it for 2weeks way back in college and last year.. but still, i am worried.. please help!

  • http://www.babyhopes.com/ Vickie B.

    If the tests are negative all you can do is go to the doctor and get a blood pregnancy test. It could be that something changed in your system (like the weight loss or stress) that threw off your cycle. If you are worried, you should visit your doctor to make sure everything is okay.

    This is a little complicated to explain, but I’ll try my best.
    6 months ago my ex partner cheated on me and caught chlamydia and gave it to me. It scarred and blocked my tubes. Last month I had an operation to repair it. The operation has given me a 50% chance of conceiving. I went on the pill (Yaz Flex) and it made me very ill. I went off it mid last week. My partner and I had sex last night and afterwards there was a pink tinge of blood. Since then I have a bright red mucus. Does anyone know what this could be? Could I be pregnant as I wasn’t on the pill for a full month?

  • hmmm…

    I also am in the same position as you, i got chlamydia from an ex, and the scarring caused my tubes to block..I had a scary tubal pregnancy, which resulted in the removal of my left tube and ovary..i was told i also had about a 50% chance at conception..I have been trying with my current bf to get pregnant. .and directly after intercourse last night, I , too, had bright red mucous and pink tinge..hmmm..any thoughts or answers would be great!..I can’t believe how similar our stories are!..
    good luck to you.. :-)

  • smpOak

    My Fiance and I are trying to conceive and normally my cycle is pretty regular, once and awhile might be a day or two early or late, this month my cycle was supposed to begin on 12/02 (took a pregnancy test on 12/03, it was negative) 6 days later it started on 12/09 and lasted for 7 days. This has never happened before my periods are only ever 5 days. I usually have very heavy periods with painful cramping, I didn’t have either of these it was a lot lighter then usual and no cramping at all. Now it is 12/19 and yesterday I had a brownish color in my cervical mucus, and today it is light pinkish. I am just wondering is it possible I could be pregnant or what other reason could cause this?

  • LilMomma

    I was breastfeeding for almost 9 months and got my period back twice. Now Im on day 37 tomorrow, no period. I kept feeling like Id start almost two weeks ago and again since a few days ago. I had a couple very small bits of pink tinged mucus a couple days ago instead of a period. Should I test or just wait? Why would I have the pink tinge so late in a cycle? Is this just normal after breastfeeding?

  • http://www.babyhopes.com/ Vickie B.

    It could just be how your body is. If it is worrying you, you should go and see your doctor.

  • http://www.babyhopes.com/ Vickie B.

    It could be that your period was just about starting.

  • Someone

    Hi. I have irregular periods. My cycle is as early as 20 days and as late as 38 days. But for the past couple months it has been 33 days. So my period this month should come on the 27th/28th. Now its the 23rd. I just started the habit of checking my cervical mucus myself. Today i saw a few specs of blood ish dots in my white cervical mucus. Any idea what it may be? I’m trying to conceive btw.

  • flossyflower

    I have a 35 day cycle. I ovulated on the 24th july-26th july, 1st august I had mucus with red blood streaked through, now I its pink mucus nothing more.. I have 8 days until next due. Is this implantation bleeding? Weve been trying 3 years for our 2nd child.

  • http://www.babyhopes.com/ Vickie B.

    It could be. If you take a pregnancy test in 3 or 4 days, you may be able to see a positive result if you are pregnant.

  • cc
