I've had the implant in for almost 2 years now and I've been on and off with periods. Ive been backwards and forwards to the doctors to see if there's a problem but they can't see anything. But I'm currently having a period and I've been on for 2 month straight now, almost 3! Is this normal? I used to be on the pill before this but I never used to take it on time so got the implant as an alternative option. Am I better off getting it taken out?
