I Don't Know What's Wrong With Me.

Destiny
Me and my husband have been TTC for 2 months and my periods and have been 28 day cycles but I just got my period 8 days early, I'm on my 2nd day. I also started feeling nauseated and threw up after I ate and looking at food makes me sick. I have never had this problem ever and I don't know what to do. Me and my husband are very worried.
