Sometimes my BH contractions feel like menstrual cramps right before the tightening of my uterus. These are just practice contractions to help your body prepare for the real work of labor. One thing to know if you are really in labor is to see if the contractions go away by trying to drink some water, change position (if lying down get up and move, or if moving around lie down on your left side), try to go to the toilet (sometimes I get more BH when I have to pee or poo). Also, before going to labor and delivery, you might want to wait until you are far along in the labor process. For example, you can't walk or talk during a contraction, they are coming at regular intervals, and you can't take your mind off of them--can't be distracted from them. I'm sorry if I sound preachy about going to l&d too early, but I really feel that is why DD was a c-sec, because I got there and was put through so many medical interventions--pit, epidural, antibiotics, c-sec with epidural window, c-sec under general anesthesia, not seeing my DD until she was over 4 hours old, DD having tons of bloodwork, glucose solution, formula, etc. . .It was hell!
