"been on camrese for about 3 years, after trying 2 other birth controls. for the first two months you will have a lot of spotting, but if you push through those two months it goes away completely. i haven&#039;t had any spotting in months and used to have an extremely heavy period. i have endometriosis and this pill helps a lot. if i forget a day by accident, i will have endo pain the next day almost immediately. i did use to break out the first few months as well, but not anything anymore. no weight gain or any other side effects."
