I am looking into an iud and going blankly into this I get it Monday but can't decide rather to just get back on the pill or if the iud will be a better option.. What I am wanting to know is if they really work.. Like if he doesn't withdraw will I get pregnant with it? And does it really last three years? And will he be able to feel it? Can I still use Tampons on my period? Sorry for all the questions I want outside info and not from just my doctor he is male and I kinda need female advice
