2 weeks before my expected period.

Okay question! I'm two weeks away from my period but I have been feeling very nauseous on and off these past two days. I've got some weird cravings and some of my favorite foods just do not taste the same to me anymore. I do have endometriosis, I did have surgery to remove most of it. I do still have a little bit but not much, me and my husband just visited with my OB/GYN when I was on my last period and he advised us to try and get pregnant to help get rid of it. We started trying ASAP and I'm taking prenatals as advised daily. So my question is could I be having early pregnancy symptoms OR could it just be my body being weird?
