So I've been on the implant since I was 14, had it changed when I was 17 and never had a period or spotting the whole time, now 2 years in on my second implant and I've been on and off bleeding since march?! Sometimes I'm bleeding for 6 weeks straight! I went back to my doctor and they changed it as they said it could have a different effect every time and I've just come off another 6 week period a few weeks ago and now I'm back on, what do I do?!
