E.W.
I did Depo from 18 - 21 and then stopped it (because I didn't like the side effects and because I didn't think it was good to not have a period for that long). The side effects I had were when I first went on it I had my period for 3 months...my doctor ended up having to give me a pill to make it stop after the three months...I gained A LOT of weight (went from size 5 to 11 and I was exercising and watching what I was eating)...I had a major decrease in my sex drive too. When I stopped it I went on to the pill and then the patch for a little bit - didn't like either of those at all. I switched to Nuva Ring and used that until my hubby and I conceived #1 (I was only off Nuva Ring for a month - after Depo we tried for over a year to end up miscarrying). Now I'm back on the Nuva Ring after #1...I won't switch...I LOVE it. I don't have any side effects from it at all, and my husband cannot feel it (nor can I) and it's NEVER fallen out.
