4 weeks pregnant

Last night before I went to bed, I experienced bubble guts (diarrhea) and felt like chills were coming on. I went to the restroom and when I came back fell asleep. I’m up now and my stomach is still making noises but no chills. Is this a sign of something bad happening (like miscarriage bc when I googled that’s what it showed) or most likely something bad I ate (or stomach bug)

I’m really scared we tried really hard for this baby 🥲
