Hello! For almost two weeks now, I've been having diarrhea with cramps at night, once even vomiting. This evening I woke up again to go to the bathroom, and there was pain in my lower abdomen, diarrhea. My stomach felt hard every 5-6 minutes, and if it was just a feeling of pressure before, this time there were pains in my lower abdomen. I struggled for an hour, then managed to fall asleep. The last three days have been very bad mood, I can't think straight and constantly feel inside myself, I don't want to talk to anyone. In my first pregnancy, I never had such a thing, gave birth on the 42nd week after a portion of castor oil
