Mirena
birth control
"Awful. I had such high hopes for it. I expected to bleed for a bit before it tapered off and regulated. I was willing to wait it out until the hormones were in my system. I bled for 5 months. Not heavy, but enough that I'd need a light tampon. I also started shedding hair at an alarming rate. 
Pro: Not pregnant (it's easy to not get pregnant when you aren't having sex though, due to constant bleeding)
Pro: Not ultra tampon heavy like I was on paragard
Con: Nonstop bleeding, bad clotting, all the damn time.
Con: Hair loss"
