Estrostep Fe and sex drive

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.

Since I have been on Estrostep, which I started taking it about 3 months ago, I have been very moody. I get mad and sad for no reason. I cry alot and I stay depressed most of the time. Also my sex drive has increased .. alot. And when I started taking the pill, my period was very irregular. It would stop for a day and then start again the next day .. or stop and 2 days later it would happen again.

i have noticed severe mood swings and a HUGE increase in sex drive.

This might seem strange, but I've noticed a drastic increase in my sex drive since I've begun taking it a month ago. Anyone else?
