Pregnant but help pls

2 days ago I found out I was pregnant again after a loss in December ♥️ I’m super overjoyed ♥️ HOWEVER.. today I am in pain and literally feeling like I can keel over and die. The nausea is SO BAD, I look at food and want to projectile vomit. Even water smells bad. My OB told me to mix 25mg of Vitamin B6 with Unisom pills and that would create a non prescribed but prescription strength nausea medication that I can grab OTC… it’s not working! I can’t stomach anything, what can I do to help I’m going nuts. I was on zofran for my 1st son but now studies say it can cause birth defects?! I also have this MASSIVE MIGRAINE and Tylenol is doing nothing and I obviously am not going to go crazy popping pills. Does anyone care to share some tips to help me please! 😫
