IUD vs. The Pill

Evelina
Okay guys so I need some advice, obviously I'll talk to my gyno but I just want some of your guys' feedback as well. So I was taking Gildess Fe for about a month and it gave me terrible side effects. I was sick and throwing up all the time, I had constant migraines and it was just not worth it. That was the first form of birth control I had tried and the effects were so bad it made me a little scared to try any other brand of pill. So I've seen a lot of talk on here about IUD's and have been curious what you ladies think about them?? Does it hurt when they put it in? Does it change the feeling of sex, for me or him? (I'm scared if we get super rough it'll fall out. lol) How accurate is it at preventing pregnancy? I would just like to know any and all feedback you have, whether good or bad! Thank you girls!
