I have polycystic ovary syndrome (PCOS) and had unprotected sex, and took Plan B about 15 hours afterwards. I know I'm suppose to get my period a week after I take the pills , but because I have PCOS, and my period doesn't come regularly, will I have my period regardless if I am not pregnant? I know Plan B can make your period come late or early, but, how will I know I will get my period if I am not pregnant, but have PCOS.
Usually, to know if Plan B worked in preventing pregnancy, you should have a menstrual period at the expected time or within a week of the expected time. If your menstrual period is delayed beyond 1 week, you may be pregnant and you should get a pregnancy test and follow up with your healthcare provider.
With Polycystic ovary syndrome (PCOS), you may have irregular menstrual periods, or none at all. So, after taking Plan B you may have a menstrual period within one to three weeks. If this does not occur, you should get a pregnancy test, and follow up with your healthcare provider. I would encourage you to have a contraception consult with your healthcare provider and to use condoms with intercourse, not only to prevent pregnancy, but to prevent sexually transmitted infections.
