How can I stop from vomiting?

I’ve had a cold for the last few weeks and thought I was in the clear. This morning I woke up at 1 am with a fever. I used a few different thermometer’s but all of them said I was at about 96 degrees. That was weird. Then I had to run to the bathroom and I projectile vomited twice. Then at 3 am my fever broke. At about 5 am I woke up again with a fever and puked green bile a few times. My husband told me I needed to eat a piece of bread and drink a little water and see how long I could hold that down. After about 30 minutes I vomited that. Then at about 6 I vomited again and I think that was bile. It was bitter and yellow. Then at 9 am I puked bile a few more times. I’ve had a few drinks of water here and there and nothing to eat. I can’t keep it down and actually I don’t want to eat. I’ve slept pretty much all day. I don’t know if I have the stomach flu. My husband and son ate what I ate the night before and they’re fine. I took some pepto bismal and vomited. Is there anything else I can do to alleviate the nausea? I just need to know if there’s anything else to make me feel better.
