birth control
"I decided to write about my experience because reading about other women's experiences with this type of birth control is what ultimately helped me...
I've had paragard for 6 months 
The first 3 were rocky. I did it on a Friday morning caused a huge cramp as did insertion. I took 800 mg of Advil, Valium and a loratab about an hour before (none of which was prescribed..just extras I had around from wisdom teeth removal)
After insertion there were no cramps but on the drive home they started. That Friday night was terrible. I had no spotting but only a bottle of wine and lots of Advil cured the cramps. 1 UTI, 1 case of BV,  and 1 month of constant back pain later I'm happy with the IUD. Periods do still last 7-10 days, not as heavy though."
