birth control
"I had this for almost three years. 
The first time I got it, I couldn't even do a squat, it was so painful. I also had heavy, long periods. I had it removed after 8 months. 
I can't take estrogen, and the mini pill sucks. So I tried paragard again (this time for almosy 3 years). 
I bled all of the time. 
14 day periods. 5-7 days of ovulation bleeding.
I bled 20 days of the month. It was positioned correctly. Nothing was wrong with it. 
I didn't get pregnant because I could literally never have sex."
