Okay so I used to be regular, then I used the depo provera shot for almost two years decided to think about having children so I came off it but my doctor advised me to use the pill/patch to help regulate me and kinda force my body to have a period. so I started taking the pill for about 9 months seemed regular then I stopped taking it and ever since I have I've been so irregular, but not like I'm not getting a period... I'm getting them so close together for so long, and it's so painful! I spent four solid weeks bleeding but I thought it was just break thru bleeding and my body purging from long use of bc, it's not been 5 months off it and it's so bad, I get positive opks but then a period 4 days later? It doesn't make any sense and my doctor just seems to say, go back on the pill to regulate yourself! To me that doesn't make sense because as soon as I come off it again everything will go all out of whack and off track. Does anyone else have this issue or had it and there was a reason? I'm in desperate need of advice.
