I was on the depo shot for over two years, prior to this I never got a period regularly. After the depo I stopped BC all together for over a year and no consistency came to my periods. I have recently started the pill (seasonique) about 2 months ago, I do have unprotected sex with my fiance', not trying to get pregnant but not avoiding it. The past week or two my breast have been extremely sore and abdominal pain. Can I even get pregnant? Should I get off BC to regulate my periods or does BC help that? I know there is a difference between BC periods and natural periods. If anyone can help in any way I'd greatly appreciate it!!
