I know I'm not having real contractions yet but I've been having BH, I think. My stomach keeps getting really tight but no pain. But the underside of my stomach doesn't get hard, only the top and front. 
When it's a real contraction will my whole stomach get hard?
TIA. 

Re: Contraction ?
The OB nurse told me if your belly is as tight at your forehead you are having a contraction.
She told me this because apparently I'm having them, but not feeling them.
BH do hurt!!! My belly gets hard up top but not at the bottom as well. I have cramps that sometimes start through my lower back and moves to the front and sometimes its just the front lower area. It definitely stops me in my tracks and last like 2 minutes and thats it. I'm also 2 cm dilated and 1/2 effaced as of Tuesday!!!
Good Luck!
