Hello, what were your pre-natal signs? I can't understand if it's just pain or false contractions. My belly sometimes hurts like during my period, not every day and the lower abdomen clenches, it feels like my stomach is falling down ??‍♀️ It's an indescribable feeling. Yesterday before bed, the lower abdomen clenched but it was bearable and my back aches every day. It's probably around week 37, only now do these pains start to feel real. Has anyone else experienced this? I'm going to see my gynecologist soon, I'll tell her how it is ?
