Good day. I have such a question... Yesterday my stomach hurt all night and I was constantly running to the toilet with strong diarrhea... As soon as I went to the toilet, the stomach stopped hurting... I thought it was contractions. The stomach hurt not from below, but from above... It felt like I got poisoned, I felt nauseous and it was freezing for about 40 minutes. Then in the morning everything passed. Now I'm worried about the baby, and now it moves not so actively... Should I call an ambulance? Or is this normal? Maybe inactive because I've slightly weakened?
