What is Implantation Bleeding?
We have recently had a number of questions about implantation bleeding on the forum. I thought it would be useful to pool together some information on implantation bleeding to help our forum members who are actively trying to conceive.
Implantation bleeding is thought to occur in around 25% of all pregnancies. It is caused by the fertilised egg implanting itself in the uterus. This implantation can cause some of the uterus lining to be dislodged and result in the implantation bleeding.
In a regular 28 day menstrual cycle, most women will ovulate between 12 to 14 days before their period would start. Implantation occurs around 10 to 14 days after ovulation. This means that if you are going to experience implantation bleeding it would occur just before or around the time your period is due.
Some women incorrectly interpret the implantation bleeding as a light period and assume they are not pregnant. A pregnancy test is the best way to ascertain if you are pregnant; most home pregnancy tests can be performed from the day your period is due although some doctors recommend waiting to test until a week after your period is due. Implantation bleeding is different to a menstrual period bleed because implantation bleeding tends to be: brown or pink, light and it will not become a heavy flow of fresh blood. It can last from a couple of hours to a few days (i.e. it is shorter in length than a menstrual period bleed). Some women experience mild cramps with implantation bleeding but these tend to be less severe than period cramps.
Did you experience implantation bleeding when you became pregnant? What was it like?
