I had a miscarriage late last October, right after the miscarriage I started birth control, Viorele to be exact. I've been on it for about 4-5 months now and I have started to have spells of severe lower abdominal pain. It's happened 3-4 times since October. There is no set time of the month it just happens with out warning. It can be so intense that it radiates into my lower back. It isn't like normal menstural cramps they are more like contractions. My mom thinks it's just the birth control but I don't think so. Is Viorele known to cause these?
