ive been on nexaplanon for about a couple months now march will be a year ever since I got on it I've been having irregular periods , very , very heavy bleeding . I lost a lot of blood I became anemic .. But then my period just randomly came on after it didn't come on for a while month and me and my boyfriend have un protected sex all the time and we also had sex when my period was on and that was like 2in a half months ago and I haven't had a period since ... Could I be pregnant?
