Hi there! I have Mirena and got it for 2 reasons - the main reason is because I never want to have kids so I don't see any reason of having my period. The secondary resaon, of course, is for birth control but that's not really necessary because my boyfriend is getting a vasectomy. So far I love Mirena! The procedure for getting it inserted was really painful but my doctor said it hurt me more because I've never had kids, and my cervix had to be dialated, etc. After that I had light spotting for about 2 and a half weeks. I was even able to have sex just 3 days after getting in inserted and wasn't in very much pain. My boyfriend can't feel the strings and it hasn't changed my sex drive at all - we have a very passionate & active sex life too, so that's definitely a good thing! I haven't gained any extra weight either. I has helped my periods too. Mine used to be moderate to heavy and last 7-8 days. I have a period once about 3 months (sometimes longer) and it's just like spotting for a couple days then it's over. I haven't even used tampons (the thong pantyliners are thebest invention ever, haha)! I can't think if I'm forgetting anything, I hope this helps!
