Contraction? Help?

Rania

Hi guys

This is my first pregnancy

I am 37+6 rn

I am having pains in my lower back and lower abdomen somewhat like cramps.

They are bearable but they hurt.

Idk how to time them. I tried walking and changing positions they did not stop.

I'm not even sure if these are real pains.

I had some cramping before and was told they were braxton hicks.

I am confused what to do.

I had diarheas aswell.

Is there any way I can be sure that I am having labor pains?
