My period is SO screwed up! My fiance and I have chosen to be celebate until our wedding night so we KNOW that there is never a chance of pregnancy. But sometimes I'll go a month and a half without it. Then when I do get it, it hits me hard and lasts for about 10-12 days! I used to be on the birth control pill for this reason, but I had surgery last year and had to stop taking them. Due to health insurance reasons, I wasnt able to go back on them. When I was on them my period was fine! Always on time, I was always prepared and always knew when I was going to get it. If this has happened to you before, maybe you should talk to your doctor about going on the birth controll pill! Hope this helps and I hope you get everything straightned out soon! I know it can be annoying!
