How Long After Conception Does Implantation Bleeding Occur?
When you are trying to get pregnant, you are always looking for clues to let you know that your hopes and dreams are on their way to being reality.
One of the initial signs that women look for, as a sign that they are pregnant, is implantation bleeding.
What Happens Before Implantation
Before implantation bleeding is a possibility, there are several steps that need to occur in your body.
On average, your ovaries will release an egg (ovulation), into your fallopian tubes, 14 days before your period is due. Your egg will survive 12 to 24 hours after ovulation, and then will start to disintegrate, making conception impossible.
If your timing for intercourse is good, there may be a lucky sperm waiting to fertilize the egg (conception) upon release. Healthy sperm can survive up to 5 days after ejaculation in the woman’s reproductive tract. Optimally, having sex, as close to ovulation as possible, will increase your chances of conception.
Once conception has occurred, the fertilized egg, will travel down the fallopian tube to the uterus. As the egg is traveling, the cells will continue to divide and grow in size. When the egg arrives at the uterus, it will attach to the uterine wall (implantation) and start to produce the hormone that pregnancy tests detect, hCG (Human Chorionic Gonadotropin). The time required for the egg to travel to the uterus and implant is usually between 7 and 10 days.
What is Implantation Bleeding?
When the egg implants, some women experience implantation bleeding. You may notice a small amount of blood when you wipe, after using the bathroom. The blood is typically a light pink or brownish tinted color. The amount is much less than when your period starts. When the egg implants in your uterus, it develops a layer of cells, trophoblast, which surrounds the egg. The trophoblast provides nutrients to the growing egg by burrowing into the uterine wall. As it pulls the egg into the endometrium, a small amount of blood can leak into the uterine cavity, causing implantation bleeding. Implantation bleeding does not occur with every woman. Usually only about 30% of women will experience implantation bleeding. You will usually see implantation bleeding 4 to 7 days before your period is due if you are one of the 30%.
If It Was Implantation Bleeding, When Will a Pregnancy Test Be Positive?
Chances are, if you are reading this, you are trying to convince yourself that the bleeding you are experiencing is actually implantation bleeding. As much as you would like a definite “YES! You are pregnant!”, the only way to be sure is see the positive pregnancy test result. Luckily, you don’t have wait too terribly long to be able to get accurate results from a home pregnancy test. If you experienced what you think is implantation bleeding at the six days past ovulation (DPO) mark, you may be able to get a positive pregnancy test in about 4 days which is typically a bit before your period is due. If implantation occurred closer to 12 days past ovulation, you may have to wait until your period is actually late to test. It typically take about 2 to 3 days, after implantation, for there to be enough hCG (the pregnancy hormone) in your urine to register a positive on a sensitive home pregnancy test.
