Very sick, help!

Olivia
I am 12 wks and have had a very rough first trimester, I've lost 20 lbs and still am vomiting multiple times a day and recovering from a ruptured cyst. I was given nausea medicine but it's to the point where I can't even keep that down. I'm afraid I'm going to get dehydrated, does anyone have any tips that helped them? I'll try anything at this point!!
