Recently I've tried new birth control, an implant in the upper arm called Implanon which have similar side effects to birth control "Depo Provera" the shot. I'm worried about my period; I haven't got any after I removed it. It's been a month now since the removal and nothing. I've had post menstrual symptoms like pain and sore breasts, but my breasts were sore while on the implant, and still nothing. Before I took this birth control my period was like a clock and now is completely ruined! I know that it seems like I can be pregnant but it's very unlikely; I did not had sex after removal and always with protection before removal, moreover I took a pregnancy test so the result came back negative. I would like you to exclude the idea of being pregnant from start and focus on real like problem. I personally think it is a side effect, or I don't know yet. I don't know what to do and I'm really worried about getting my period working normally, furthermore is very bad for a woman's health not having her period when she should! Please let me know any information about how long after this birth control removal a period usually comes back. I think there may be some women who used it.
