endometriosis
"Due to blood clot and diagnosis of autoimmune clotting disorder (anti-phospholipid syndrome), I had to be put on a non-estrogen birth control to help with my endometriosis.  The pill has caused me to spot just about every single day and I have been on it for over 6 months.  It has not been able to control the cramps and I have to have 800mg ibuprofen on hand at all times.  It has cut down on my 7-10 day very heavy period, but since I spot every day; not sure if its really helped with the blood loss and anemia.  When I started, I had just about every symptom of pregnancy; but I was not pregnant.  This went away after about 1 month of use.  Unfortunately, this is my only option at the moment, so I'm kind of stuck with this."
