Maybe food poisoning? Pregnant

So I’m 14 weeks and 6 days pregnant and for dinner we had Pizza Hut. It’s now 1 a.m. and I woke up with feeling nauseous like I’m gonna puke with horrible cramps and literally pooping liquid diarrhea non stop. You think maybe food poisoning? anyone else went through this?! IDk if I should go to the ER or not.
