nausea needs to go away

So I am in my 7th week of pregnancy. Not going to lie from finding out I was pregnant during the fourth week it has been a complete nightmare. In and out of urgent care, OBGYN, and yesterday was in the hospital for the whole day. This friggin nausea is so debilitating. It's exhausting. Hospital gave me IV fluids and zofran helped. But sent me home. Ugh. Wish they kept me over night and gave me another dose. Please anyone give me some words of wisdom. Struggling badly.
