I haven't had a period since getting off of depo in july, of 2015. I am on tri previfem. I am on the second week. I will take the first blue pill tomorrow, I'm wondering when might my period come? I was told by my OB, that I will start if I finish this pack of BC. I'm concerned that my period might never come because of depo Provera. I was on depo for a year.
