What is the probability that it is a pregnancy?

If you are taking a contraceptive drug, you do not have fertile and infertile days, because hormonal contraception blocks ovulation. In this case, the use of emergency contraception may be prompted by a possible error in the use of the method, which cannot be corrected using the guidelines from the leaflet. It is not clear from your entry whether there was actually a need to take a "pill after", and thus - it is difficult to answer whether pregnancy is likely. When using certain types of contraceptive pills, there is a so-called withdrawal bleeding. In some cases, it may not appear despite the absence of pregnancy. Taking the "after pill" does not protect against pregnancy in the event of further unprotected sexual intercourse or if the contraceptive method used was used incorrectly. If you have any doubts, I suggest you simply take a pregnancy test.
