So, for the most part, you've all had positive experiences with IUD's? I was on the pill (Yasmin) but got off of it because I was concerned the hormones would mess with my training and interfere with fat loss. They say Yasmin is not supposed to make you gain weight, but I know my chest was bigger. But, now I'm using "the sponge" which is okay, but has some drawbacks, such as you can't really be very spontaneous, it has a really nasty tasting spermicide in the sponge, and you can only order it over the internet. So, I'm thinking of switching over to an IUD. Are their any drawbacks at all?
