Hello everyone!))) First pregnancy ? I don't know, maybe it's normal... In short: started feeling a belly, I touch it with my finger and it's hard (not exactly a stone, no, slightly firm) and it hurts a little bit (specifically when pressed) then I think "stop!" Maybe it's a spasm? I press again - the belly is firm, but not hurting anymore))) What's the question: should the belly be slightly firm like a child's ball? Or should it be soft, like the lower abdomen that doesn't pass?
