Suddenly sick!

I’m 21 weeks and thought I had a mild case of food poisoning today, thankfully I drink over a gallon of water a day, so dehydration isn’t an issue and I only threw up 3 times, I’ve had food poisoning in the past, usually hours after if it’s mild you should feel immediately better, but now after napping and such, 5 and a half hours later, my stomach is still slightly queasy. Could this just actually be baby? I have an apt to re-check my blood pressure with my doctor, so I’ll mention it but I’m curious if anyone has gone through something similar?
