I've had nexplanon for 5 months now and for the last 4 months I've had a constant period, I don't know if it's normal because I swear the doc said 6 months about something, so far that's all that has happened is non-stop period for 4 months. Please help me, I don't know if this is normal and I want to have sex, I haven't for the 5 months I've been on nexplanon but I really want to and I don't want to use condoms
