Ok. I have been taking Yaz for a month now. It helped stop my bleeding for over a month, but now I keep getting these pains through out my belly. The pain will come and go and once in a while I get the pain through my lower back. I am not sure if I want to keep taking the pill. Nurse says my body is just changing due to the pill. I just want to know if the pains are from the pill and if it will go away...
