Im 38 weeks as well and have felt that for two weeks or so id say. Sometimes its soo painful and sharpe. Saw dr last week and he says im 2 cm dialted and the pain is normal. Ftm so its all so new but baby is coming : )
It's your cervix starting to open a good sign!
No my doc told me it's the baby pressing on your cervix it's normal
It could be your baby dropping lower. They call it "lightning" because it can feel like that really quick sharp pains.
