Hello... I encountered an unclear condition, maybe someone has had something like this... Since yesterday evening, my stomach feels heavy, there was a feeling that I wanted to go to the toilet but couldn't, I felt nauseous slightly in the evening... My stomach pulled and released, the pain didn't intensify, there were no intervals...I went into the shower, it didn't get any better, a small piece of white clot came out... I ate, the food was normal, excuse me for the details, it passed through diarrhea all... I lay down to sleep, but couldn't sleep until morning, then I kind of fell asleep, woke up, there was a dull pain, but not intensifying
