Hi. Well, I started taking Estrostep back in January, but had bad cramps (worse than when I wasn't taking BC) and I was getting nauseous a lot so my Dr. switched me to Levlite. The first month was fine and the cramps were not as bad, but this morning I woke up with bad stomach cramps plus period cramping and it was very very bad. I thought I was going to get sick and I was very pale and weak. I ended up taking some tylenol and soaking in the tub and it felt better. But I don't know why I was in so much pain when BC pills are supposed to make cramps better?? Also even though I had those terrible cramps there still hasn't been any blood. Anyone else experience this side effect? Thanks.
