Bad Nausea

I’m about to be 6 weeks pregnant and I was told the nausea doesn’t get horrible until around 9 weeks but so far I’ve already been so sick and I’m scared for it to get even worse. Even before pregnancy I’ve had a weak stomach and nothing my doctor is giving me is helping. I’ve tried the sea bands and vitamin b6 and unisom and have tried morning sickness ginger drops and bubble water. What else can I try? I’m getting desperate at this point any advice is helpful thank you!
