"Lolo seemed to work fine for me for the first couple months. I was a bit more emotional than usual but wrote it off as stress and it is hard to tell if anything was caused by the pill. It is important to note that I was pretty inactive at the time aside from some walking. However, upon beginning a new workout regime I began to experience horrible cramping, similar to period cramping, and breakthrough bleeding. This was halfway through my third pill pack. I believe something about the heavy exercise prompted it, as it does with my period. In an unrelated incident, I hurt my knee pretty badly, and have taken a few days off working out. The cramps remain and are horrible. I wonder if something else is wrong with me. I want this to end."
