I need advice

Tiffany

I don't have periods unless I'm on birth control. when my husband and I decided to ttc I went to my gyno. she put me on provera 10mg. I started that last month for 10 days and got my period and ovulated. I'm confused on when to start taking my provera again. do I wait until it's time to take a pregnancy test or do I start taking it 10 days out from my projected period. my gyno told me not to take it when pregnant.
