Anyone take Progesterone to jump start period??

My husband and I have decided to try for a 2nd child!!! I'm in my 30s so I kinda want it to happen soon! I was in the depo shot for about a year and haven't had one in about 6 months. I went to the doctor for a pre-pregnancy visit just to make sure everything looks ok. The doctor put me on 20mg of progesterone for a week to jump start my period. I start it tonight and take it for a week and the doctor says I should start my period about a week after that! Anyone else been in my shoes? Did it work for you or not?! I'm so anxious!!!
