Welllll I haven't been active at all during my pregnancy. I'm 38 weeks today, so yesterday I went on a walk, did some squats, danced... took two warm baths and tried nipple stimulation, since bedtime...ive been feeling like I'm on my period.. well I don't really know if I've been cramping Because I have a high pain tolerance, but my lower body in general feels as if I'm on my period. Could this be the before stage of labor???
