I was prescribed Ovcon 35 for ongoing bleeding associated with endometriosis. I have had the mild headaches, EXTREMELY tender and bloated breasts and stomach upset others have described but can live with it. One of my concerns is that even WITH endometriosis, I have never really experienced bad cramps. After being on this for only three weeks, my cramps are really pretty bad. Secondly, I have gained three to four pounds. I am willing to stay on this and see if my body adjusts. It has helped my bleeding tremendously (so far) and I have not had the PMS symptoms I typically do. My main concern is the weight gain. Does your body adjust to it and the side effects lessen over time? I can stand just about anything but the weight gain. Oh, and by the way...I have been on a few different birth control pills for close to 20 years and have NEVER had side effects until this one.
