I am about 40 weeks pregnant and I do not feel any type of pain. The baby`s movement is enough and water level is enough too. What should I do?

I would listen to my Physician, not take advice from strangers on the Internet.

I don't know what you mean by "what should [you] do"? You wait for contractions to begin.

The date of conception is difficult to determine. Babies are often early - or late.
