I am on Femcon FE and am not too sure what to think of it. My boobs got bigger, which yes they hurt constantly, but bigger boobs is worth it to me. haha But other then that, i originally got put on this for my iron deficiency and the fact that i could not swallow a pill. I went on birth control to help regulate my period, because there was no schedule to mine. I have been on Femcon for 4 months now, and still cannot regulate my period. It comes during the 3 week of white pills and it's not even blood. It's gross brownish/red and not to mention it makes me itch. And i never got cramps before and now the 2nd day of my period is almost unbearable. Also, since its not even regulating my period correctly i worry if it's even working as "birth control". I wanna change but i don't know what to even change to. I don't want my boobs to shrink back, but I guess if i must i will. lol
