birth control
"I am 25 years old and have never been pregnant.  Due to having migraines with aura, I needed an estrogen-free form of BC.  I was on Depo Provera ('the shot') for 1.5 years and HATED it.  I gained 20lb without changing my diet, spotted for a year straight with no breaks, and was an overall mess.  Mirena was the obvious choice for me.  Insertion was not fun (<5 min.) and the 2 hours after insertion I had awful period-like cramps.  However, they subsided and by the end of the night, I was okay. The next morning, no pain!  My spotting from the Depo even lifted.  I have only been on Mirena less than a week, but so far I love it.   My anxiety definitely made the insertion process worse, so try to relax."
