Could this be it!

My last period was November 14 for about 4 or 5 days. I was getting symptoms of both on a and pregnancy I thought. I was suppose to get my period Dec 11, it didn't come u til the 15 or 16. so had normal period then. symptoms went away. starting Friday the 22 I started with these symptoms against. queezy and nauseous. intense acid reflex and heartburn constant burping. I thought I would like but it was just dry gagging. it is Tuesday and it is feeling like I am hungry but I don't want any food. anyone have similar experiences
