I am 17 and I'm an Implanon user, recently I have had unprotected sex with my boyfriend and I have had the Implanon NXT for almost a year now. I usually have two periods in a month, or just the regular, but I'm late. I feel asif I'm visiting the bathroom more often and eating a lot more, but I can't be sure if that is just paranoia that I might be pregnant. I've heard HPTs are sometimes unreliable and I am unable to visit any doctors. Is it normal for a period pattern to be disturbed this far through Implanon use?
