I read so much on how great the IUD was and now that I got it a week ago I'm only been reading everything that is bad about it! I have really bad anxiety and now it's only getting worse as I'm getting super moody as if I'm on my period and reading about how women have been gaining so much weight on it? has it caused you weight gain? moody? periods? I thought this would be amazing fewer periods, no babys obviously haha but now i am starting to panic..
