amenorrhea
"I've always had VERY Irregular periods due to kidney failure. Im 22 years old and have went as long as 6 years without a period. The first time I was prescribed Provera I took 1 10 mg pill a day for 10 days. It took 2 weeks to get my period, I was so excited because I didn't think it was going to work for me. My period came back for 6 months without missing a beat, after it stopped coming I had to redose and I'd get it for another 6 months at a time. I was having the worst time falling but finally a miracle happened for me! If it wasnt for provera giving me my period Im almost certain I wouldn't be holding my baby girl in my arms. I would give it a 10 rating if it wasn't for me having to redose so often"
