birth control
"Ok, I went on it obviously to prevent pregnancy but also to help with my painful periods. Pack one, I had breakthrough bleeding about two weeks after my normal period (pre BC) with no withdrawal bleed. I had extreme headaches, nausea, and anxiety. Pack two, same side effects but had a normal withdrawal bleed. Pack three, the side effects went away and my withdrawal bleed was less than normal. Super easy to care for. Pack four, my withdrawal bleed was abnormal. It lasted the entire four days of brown pulls but it itself was brown and not red. Pack five's withdrawal bleed started out brown and ended like a normal period. Color and all. My anxiety was so bad about pack five that I took two pregnancy tests just to rule out the weirdness."
