Medroxyprogesterone question

Shari

I gave birth to twins almost 10 weeks ago and I have not had a period yet I thought I might of been pregnant again and luckily I am not my OBGYN prescribed me Medroxyprogesterone but I am scared to take it because I want my cycles to be normal again so is there anyone that took Medroxyprogesterone and did you eventually have normal 28 day cycles? And when did you start your period while taking them?
