Food poisoning pain

I think I have food poisoning. Sudden and several abdominal cramps and indigestion. No vomiting or fever but very nauseous.

Anything I can do to relieve the pain/discomfort? It's been like 1.5 hours since it's started. (Had sushi from a usual, go to restaurant, shocked but pretty sure that's what caused it).

It's past midnight and my two year old is asleep, can't really leave her and go to ER (unless it gets significantly worse). Also, 7DPO, really scared about potential side effects/affecting the potential for pregnancy this cycle.

Anyone have any tips?
