22 weeks and still nauseous

Ri

I’m 22+1 today and still feel nausea all day long, every day. I am taking two different medications, I changed my prenatal four times, I tried different foods - nothing changes. I don’t throw up often, maybe twice a week, but I can’t bend down or brush my teeth without feeling really really sick. I canceled our last vacation, because I can’t ride a train, car or plane. Is anyone in the same boat?
