Question about fights! I have lower abdominal pain, a bit in my back. But the pain doesn't just grab...it even cuts like it does...is this normal? The fights are very big and then they pass, for now. I already forgot what they were?until they become more frequent...but scary pains. A little chills me...It feels like during painful periods...there are no changes in discharge. The baby is moving. I would like to understand what it is ? so that the husband can come and take her away if something happens.
