Help on regulating menstral!!!

Kara
Here's a run down of what I've been through this past year.. pregnant in October. Found our in November. Baby lost heartbeat 3 days after chtistmas. Husband and I found out on January 7th. Had a d&c on January 18th because my body wouldn't let go of the pregnancy. Af returned in February and march. No period all month of april. Got af in may and June and now it's July and no period in sight. I am 2 days late. Cd36 today. I'm thinking of trying vitex but I'm kinda scared in case I get pregnant. What can I do to help regulate my period? It's making it so hard to conceive. And sex isn't helping to bring on my period
