throwing up

how did you manage did you drink lots of fluids? I don’t want to pass out or anything. i’ve threw up twice within 30-45 minutes and I tried eating something light and drinking water but I feel a bit lightheaded and still nauseous 😩 I never dealt with this so idk what to do.. I have two toddlers and i’ve prone to feeling faint with my pregnancies just don’t want the worst to happen you know?
