"i am a 37 year old woman who has never had a child.  i switched to mirena from seasonale birth control because i get migraines with visual auras.  taking an estrogen based birth control pill is contraindicated in women with visual aura migraines as it increases the risk of ischemic stroke.  i had the insertion done this morning and it took about a total of two minutes from the time the speculum was inserted, tenaculum used to spread the cervix and then the actual insertion of the mirena.  on a pain scale of 1-10 (10 being the worst pain) i would say it was about a 7.  the uncomfortable part to me was when the tenaculum was used for cervix separation. two hours later all i have is mild cramps."
