Unsure... anyone else have this happen

I have been feeling nausea and vomiting in the am and sometimes throw out the day. I have also been very tired for the pass 3-4 days. Im very bloated. My period should be here in 7days. But have never felt like this before my period. I have also been more hungry then usual. With light headaces.We have been ttc for over 1 1/2years. Im just wondering if its all in my head or if Im coming down with a cold or if we might be pregnant.
