Birth control

Christina
Okay, so it's been a while since I was on bc, but when I was I took the pill and my period got heavier and longer, so I stopped taken the pill and my period kept the same flow and heaviness. I'm currently looking to get back on BC to shorten and lighten my period. My cousin told me to get meraina(sp?) But I've heard sooo many horrible stories about it that I'm scared. I'm 26 soon to be 27, I don't have kids nor do I want them anyway....does anyone have any ideas on BC? I'm clueless and scared to talk to anyone about bc for fear of being talked into something that I don't want or could cause more issues
