I am 37 weeks pregnant tomorrow.

My husband got home around 7:45 tonight from work and ever Since he got home I’ve noticed this cramping tight feeling where the baby is at and it comes in waves but I haven’t timed the waves just thought the baby was sitting in an uncomfortable angle.. but giving him time and feeling him move around I still feel this cramping feeling and it’s gotten worse as the night has gone on. I’m currently bouncing on my ball right now. I can talk through them fine but it’s just super uncomfortable. This is my first baby and I don’t know what going into labor is like.. could this be labor?? I will share a picture of my belly with arrows pointing to where the cramping is coming from. It feels like sharp pressure pushing down on my uterus.
