When You Have No Implantation Bleeding

When you’ve been trying to get pregnant for some time, any indication that you might have met with success can be encouraging. That waiting time – the two weeks or so between ovulation and a possible positive pregnancy test – can be excruciating. For some women, implantation bleeding can be taken as a positive sign.

To understand how implantation bleeding can be a sign of pregnancy, you need to know exactly what causes it. When a fertilized egg implants into the wall of the uterus, it produces a relatively small amount of bleeding. The trophoblast – which is a tissue that forms around the fertilized egg – helps to bring the egg into the uterus. During that process, the trophoblast may damage some of the mother’s blood vessels. This leads to the leaking of blood, and thus you have implantation bleeding.

Implantation bleeding is usually low in volume. It’s typically pink to brownish in color. It happens typically about seven to 10 days after conception. If you believe you have started a period, but the bleeding is scanty, pinkish, spotty, and doesn’t follow a normal flow pattern of a period (from light to heavy and back to light) it is probably not a period, but rather it is probably implantation bleeding rather than the start of your period.

Unfortunately, implantation bleeding isn’t always easy to recognize. Some women may think that they’ve started their period a bit early. As such, it can be more of a disappointment than anything else. On the other hand, some women hope to see implantation bleeding, and are disappointed each day that it doesn’t happen.

Around a third of pregnant women will have some degree or another of implantation bleeding. A lack of implantation bleeding doesn’t seem to indicate a problem with the pregnancy in any way. The presence of implantation bleeding doesn’t guarantee a successful pregnancy, either.

For the most accurate results, you’re always better off waiting until you’ve missed your period and taking a pregnancy test. Anything else can add to the stressful cycle of hope and disappointment that many couples who are trying to conceive face.
