Loestrin 24 Fe
"I started taking this pill five months ago for terrible cramps. The first 3 months were fine. The period was regular and the cramps were nearly non-existent.  My mood has been up and down, and I am always tired. Last month I bled for over 2 weeks and this month I had only a tiny bit of blood. My boyfriend and I use condoms every time just in case so I'm pretty sure I'm not pregnant. It's very scary not having a period."
