abnormal uterine bleeding
"While I was on Ortho Tri Cyclen, I was hospitalized. I came very close to needing a blood transfusion. Halfway through a pack, I started to bleed heavily. I went to the ER and had ultrasounds done to be sure I wasn't having a miscarriage or cyst rupture. It was explained to me that the added hormones were not balancing well, which was causing one to crash and cause heavy bleeding. I was immediately taken off of birth control. I won't ever try it again. It was a very scary experience."
