"i was given medicine to take before the procedure and after, it was a little painful but nothing to serious. the rest of the day i was drowsy but had no cramps, headache or normal &quot;period pains&quot;. i absolutely love the mirena and it was well worth the money. much better than the pill or shot you could take. i would recommend this to everyone! i got it the second day of my period and it lasted only 2 more days. i got it 3 months ago and haven&#039;t had my period since! as for sex i had it the 5th day and am not pregnant and have no side effects. definitely recommend this!"
