Food poisoning and baby?

Kellen • Pregnant with baby #1 after months of TTC and large weight loss. Hubby and I couldn't be more excited!
So this will likely be TMI but I'm learning quickly that modestly while pregnant wears off quickly haha.
Last night I ate dinner around 7pm, 4oz mahi mahi, broccoli and brown rice. Then had two tablespoons of peanut butter. Well 11:30pm rolls around and I wake up rather abruptly with cramps and nausea.
It came from both ends and it was pretty hard, like intensity wise. It lasted about 30 mins and my body was completely covered in sweat.
It's hard for me to pinpint what I could have eaten to make that happen. I have my very first appt with my OB at 8 weeks (feb 23)...should I try to get in sooner? Is there anything that could be done should I have gotten listeriosis? I also made sure to fill up on water after it was all over so dehydration isn't a problem
