Sharp stabby feelin down there?

So I asked at my appointment about this. She said its normal with successive pregnancies. It actually can and probably did happen with all 3 but much closer to the end. She said I probably didn't notice it as much then because of all the other aches and pains of the end of pregnancy. Everything hurt and was sore and swollen so I maybe didn't notice it as much. She said it can happen earlier with later pregnancies bc the muscles and ligaments holding everything up are weakened and so the baby is already really low and putting pressure on my cervix and all the nerves down there. She said not to worry- it won't dialate me or cause preterm labor. But it will be painful and uncomfortable. I guess I just need to get off my feet whenever I can. Ugh! The joys! Lol
