I've taken Estrostep for at least 7 years now, and I thought I have been symptom free until just recently I started to question some unusual symptoms and if they were caused from my birth control. I've had terrible bloating and constipation for the past year and I am thinking I might have a bad reaction to eating wheat, but I've never gone off the pill since I was 14 so I don't know. Also I find it IMPOSSIBLE to lose weight. I am a very serious triathlete and I train 12 hours a week, two to three times a day most days and cannot lose even 5 pounds with a perfectly clean low calorie diet. My sex drive is completely in the dumps and has been for years. It causes a lot of problems with my boyfriend and I but I'm afraid to stop taking the pill to see. I've tried Junel Fe and ortho tri-cyclen and felt that each made me gain at least 15 pounds with no diet change.
