I just had Implanon put in and my OB told me it could take up to 6 months before I got a regular period If I had it removed. But if your having unprotected sex you could ovulate and not know it and become pregnant.
sometimes after having implanon removed, you may not get a period for upto a year and a half, mine started within a few days and me and my partner tried to conceive for the next cycle and gotten pregnant. you should try a home pregnancy test in about two weeks to be sure. try other contraception if you are not planning on becoming pregnant
My sister had hers taken out and tried getting pregnant. She was sure she was pregnant because she had not had her period in a long time but when she went to the doctor they told her she wasnt and it would take atleast a month for her cycle to start normal and atleast a month befor she could actually conceive.
I assume you're trying to conceive if you're having unprotected sex. As for if you could be, it's very possible. More than likely however, it's because you just got off your BC. You're not going to have a period immediately after having your BC taken out. It could be months before your body re-regulates itself and you have another again. Some women immediately pick up where there's usually would come. Wait another week and take a pregnancy test with first morning urine.
