birth control
"2 stars because I didn't get pregnant.  That said, I had the Paragard for a year and a half.  I've never had kids, and insertion was awful, but only lasts for a few minutes.  Like many others, I experienced extremely heavy, painful periods that lasted about 7 to 8 days each.  The worst part for me, however, was the fact that I got near-constant bacterial vaginitis and yeast infections throughout the entire time I had it in.  I can't even imagine how many rounds of Diflucan and antibiotics I had.  Once it was removed, the infections went away and I've been problem-free ever since."
