I have periods every 30-40 days, they are always light. I can never tell when they are going to come. I was tested for PCOS, all my labs were perfect. I had an ultrasound of my ovaries/uterus & was also perfect there no cysts or endometriosis but we are having a difficult time TTC. I went to see my NP on the 6th (I had already had my period for the month) she prescribed me provera & said that even though I had already menstruated to go ahead & take it days 6 through 10... to have sex on the 9th, 11th, 13th & 15th then not anymore. For me to start again on the 1st of November & take the pills again for 10 days. How am I supposed to have intercourse the week after finishing the provera when that's the time frame I should be bleeding from it? I have heard very little positive things about the provera but she says I have to take it for 3 months before she will prescribe the clomid. Can someone explain to me how this works & why I should be having intercourse those days?
