Currently 41 weeks tomorrow. I've been cramping all day long. They are constant and do not change with position, but do worsen with excersise. I cannot time if they're are even contractions happening because it's so constant. I woke up about 7:30 and it lasted until about 1 o'clock when I took a nap. When I woke up from the nap at about 3 o'clock, they returned just as bad. It's been about 12 hours now. I don't notice it getting any worse. I'm worried that I have such a high pain tolerance that I won't be able to tell if it's severe enough to be labor or not. Anyone else experience anything like this?
