nausea

I'm in my first trimester about 7 weeks in assuming haven't been to a doctor yet due to insurance but I've constantly felt sick for the past 6 days throwing up every few hours and cannot keep any fluids or foods down ive tried pepermints crackers sports drinks water gingerale and even sprite and tea nothing seems to work 😔 if anyone has anything that helped them with morning sickness please give me some ideas ive already lost 20 pounds because of throwing up so much and it worries me (btw the hospital already tried giving me pills I'm looking for home remedies more than anything )
