amenorrhea
"I have never had a normal cycle, I started on birth control very young because I had constant bleeding that was almost never ending for years. I switched the type of birth control I was on over the years at least 15 times and nothing was able to control the relentless bleeding. At 24 I got married and stopped taking the pill all together, at which time my cycle also completely stopped. For a year my husband and I tried to conceive with no luck so finally I switched to an obgyn specialist who prescribed me Provera. I took the Provera for 10 days & by day 6 or 7 I had already began my period which lasted for 7 days.  Two weeks after my period stopped I conceived my daughter. I highly recommend Provera for infertility problems!"
