From what I understand Depo seems to take longer to get out of your system than the pills. I was on Mircette for a few years. Had no problems with it. Not sure why my doctor switched me. It was along time ago.

I think you'll like Kariva, especially if you're sensitive to weight gain. I tried a few different pills, and it seemed like every one of them made me gain weight except Kariva. I may have lost a couple of pounds when I first started it. I loved it! I did have some BTB with it, so when I get it again I think I'm going to try the Mircette brand name version.
