How can we distinguish an implantation bleeding from an ovulation or intercostal bleeding?
It is often very difficult to distinguish an implantation bleed from an ovulation bleed or an intermediate bleed. Intermediate bleeding can occur for various reasons, most often leading to a hormone imbalance, which in turn triggers the bleeding. This can happen at any time of the cycle.
During an inter-bleeding, the lining of the uterus has already built up, part of which is rejected. The rejection causes part of the blood to clot and the bleeding is usually brown and rather mucous. It is similar with an ovulation bleeding.
However, it occurs on the day of ovulation, about 14 days after the start of the last menstrual period. Both bleedings last one to three days and can be of different intensity. In contrast, implantation bleeding directly injures vessels of the uterine lining.Normally no mucosa is detached.
Therefore the implantation bleeding is usually bright red and more fluid. It is more likely to occur at the end of the cycle, i.e. on the 20th to 25th day of the cycle, and often lasts only one day. However, it is important to know that the blood resulting from implantation can sometimes remain in the uterus for several days before it drains away. During this time it coagulates and becomes brownish. This also shifts the time further back.
Is it possible to have an implantation bleeding despite the pill?
The pill regulates a woman’s cycle and menstrual period. Even when taking the pill, the lining of the uterus builds up every month. During the days when the pill is not taken, the mucous membrane is shed, as in a woman’s cycle without hormones, and menstruation occurs.
If a woman takes the pill incorrectly or forgets to take it, she may become pregnant despite continuing to take it. Thus, after fertilization, the egg is implanted. As a high mucous membrane has already built up and is well supplied with blood, even after taking the pill, there may be a nidation bleeding despite taking the pill. In general, however, the following menstrual bleeding will not occur despite taking the pill. If this is the case, a pregnancy test can confirm whether the previous bleeding was an implantation bleeding.
