Girls, who has had this or is having it now - very sharp pain in the upper abdomen, like stomach. Suddenly starts feeling nauseous, and at the same time wants to go to the toilet. I apologize for the details. But the pain passes quickly, and nausea is strong, and the state is semi-fainting. Weakness, and as if consciousness will be lost. And all this while the little one still pinches. I'm 27 weeks pregnant, already had it a couple of times.
