Norethindrone
"I have been on this medication since possibly the beginning of February it is now May and two months after taking it I started having constant breakthrough bleeding one day good one day bad some days clotting some days not my doctor has up the dosage to 4 pills a day which is 20mg still has not stopped the bleeding.. as of today I'm going to stop taking the pill to see how the bleeding subsides and if I get a menstrual period I would rather have a complete proper menstrual period than this constant everyday bleeding. I was only taking it to build up my blood and stop my menstrual to have a partial hysterectomy which is scheduled Aug 7th but I would rather have  a regular menstrual and build up my blood another way then constantly be bleeding every other day.."
