Feeling like crap

I’m wondering if anyone else has had these symptoms.

I’m 33+4. Two days ago I started to feel very foggy and just out of it. When I try to concentrate I start to get a headache and I feel very lightheaded. I have had horrible heartburn and been extremely nauseous with no appetite. I’m taking Zofran and still can’t keep anything down. I am unbelievably tired but I haven’t been sleeping well. I feel like every time I talk to my doctor she’s like “well you are pregnant so you’re not going to feel like yourself” and I totally get that, but I really feel like something is wrong....
