What does labor feel like ?

Quite painful : According to some people, labor pain is like a pain you never experience in any other condition. It start at the onset of labour with contractions of uterus trying to push the fetus out and doesn't end until this is accomplished, usually in a couple of hours.

How far pregnant?: Labor pains occur with regularity and feel like a hard muscle cramp--(your uterus). The intensity will increase as labor helps to bring the baby down for delivery. You should learn how to grade labor pains from very hard to just starting to feel them. Your obstetrician will teach you. Best wishes! Always let your doctor know if you have any vaginal discharge--water or blood especially.
