Bis wann Pille danach nehmen?

In principle, the earlier the “pattern after” is taken after unprotected intercourse or a prevention span, the safer can be prevented from pregnancy because the probability is simply greater to get a possible ovulation beforehand.

The pill after that has no abortive effect, but inhibits the ovulation and shifts the ovulation in the cycle of the woman by 5 days to the rear, so that no fertilization is possible anymore, because the sperms have now “pass” the egg or then died and can no longer do anything.

After ovulation, i.e. in the second, infertile half of the cycle, pregnancy is not possible and the use of the “pill after” is superfluous, because with or without a pill, the occurrence of pregnancy is then impossible.

However, since hardly one woman knows when exactly the ovulation takes place, a failed prevention at any time in the cycle is necessary and an emergency prevention can be useful at any time in the cycle.

If the ovulation happens randomly at the same time as the unprotected intercourse and the “patch after” is taken a few hours later, fertilization of the egg is no longer to be prevented. In this case, there is the possibility that a pregnancy occurs despite taking the pill afterwards.

In contrast to the active ingredient Levonorgestrel (up to a maximum of 72 hours after unprotected traffic), the active ingredient Ulipristal (e.g. ellaOne® – at the latest up to 120 hours after unprotected sex) also acts during the LH approach just before the ovulation and can thus effect a “short-term” (approximately at the ovulation).

So there is a guarantee for both “pills after” or not. With rapid intake within 24 hours, Ulipristal lowers the risk of pregnancy to 0.9 percent. At Levonorgestrel, a risk of 2.3 percent remains to be pregnant.

Happy for you!
