"i got the mirena january 2016. the insertion wasn&#039;t painful (i had a baby in november if that matters) i bled for 3 months straight. and the cramps were very painful i hated it. sex is super painful for me and i can&#039;t do it for long at all. i get headaches almost everyday, and i&#039;m very moody. but, this birthcontrol is 100% effective for me considering i use no protection with my boyfriend and he doesn&#039;t use the pull out method. and i have gained alot of weight since i got it. im debating on getting it removed but im scared of ending up pregnant again so im sticking with it for now!"
