40weeks pregnant having cramps when I lay down...what do that mean?
It means you need to talk to your doctor about it.
Sounds like contractions are starting good luck :)
you're at 9 months? Could be labor starting . Watch for your water breaking, and then start timing your contractions, and get a ride to the hospital to welcome the little one to the world!
you need to go have it checked out or its probably because you 40 weeks pregnant and also watch for labor and water breaking
Just call your doctor
Pack your bag.
