I can remember thinking the same thing when I was pregnant with Colby.

So I got DP's Aunty over who is a Remedial Massage therapist and got her to give me a massage and hit some pressure points.

Have you thought about a massage or a yoga class. Even a meditation class if you think you can relax enough.

A day at the beach is always relaxing.

On the positive side, all the stuff you're describing sounds perfectly normal and like everything is well on its well to being ready.

Chin up!
