Fertile Cervical Mucus is Like Raw Egg White

It’s concerning when you  notice blood in your cervical mucus, at odd times during your cycle.   Your cervical mucus, also known as cervical fluid, plays an important role in getting pregnant.   Through your menstrual cycle, your cervical mucus will have different consistencies.  The egg white consistency (EWCM), you see right before ovulation, is when you are most fertile.   If you are seeing blood in the mix, it is most likely due to common non-threatening sources. One of the main reasons you may see blood in your cervical discharge are implantation of a fertilized egg aka implantation bleeding.   Other common causes of blood in your cervical fluid include ovulatory bleeding and even trauma to the cervix due to intercourse.

What is Cervical Mucus?

Cervical mucus is produced by your cervix in response to the hormones that your body is producing. As you get closer to ovulation, your body starts producing more estrogen in anticipation of ovulation. The increase in estrogen causes your cervix to produce mucus that is clear, slick, and stretchy. The egg white consistency cervical mucus helps protect a man’s sperm and help transport sperm through the vagina and cervix safely.  The EWCM (egg white cervical mucus) 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 get pregnant.

Common Reasons For Blood in Your Cervical Mucus

  • Leftover Menstrual Blood – 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.  When you begin ovulation, this any blood that was trapped in the cervix will mix with your cervical mucus and cause the spotting of blood.
  • Bleeding Due to Ovulation – When ovulation begins, many women may notice the presence of blood. As your egg leaves the ovary, it may cause a small rupture in the ovarian follicle.  This can result in the appearance of a small amount of blood that will work it’s way out of your body. This is quite common and there is no need for you to worry.



Can ovulation cause bleeding?



  • Implantation Bleeding – Light bleeding or a pinkish colored cervical fluid which happens about a week or longer after you ovulate.   It can 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 discharge. 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 so it is not a reliable indication of being pregnant.
  • Cervical Trauma – Other reasons for seeing blood in your cervical mucus include ovulation and trauma to the cervix. Trauma to your cervix  is also a common cause of blood in your cervical mucus.   It really isn’t as dramatic as that sounds. Intercourse to a small scratch from your nails when checking for cervical fluid can cause cervical trauma.


Other Causes for Blood in Your Cervical Mucus



Most of the time, blood in your cervical mucus is not a major issue. If you find that you are spotting in more frequently or a heavier flow than just spotting, you may have something else going on. Medical conditions like PCOS, endometriosis, menopause, cancer and infections can all cause bleeding at odd times.  Your doctor will work with you to create a plan.

In most of these cases of blood in your cervical mucus, there is nothing to worry about.  The bleeding is usually very light and tapers off after a day or two. If you find that the bleeding gets heavier or will not stop, you should contact your doctor.   Only a physician can rule out negative causes for any heavy non-period bleeding.
