So I went to my doctor last Wednesday and was told to take Provera for seven days, then start birth control for three months while also taking Metformin. This was so that when I get off birth control I will be more fertile than I am not since I havent had a period since February. I know it hasn't been seven days, but she said I should have my period between 5 to 7 days and I have had no signs of starting. Should I contact my doctor if I haven't started by day 7 or should I just continue on with her plan?
