First time preggo here (so naturally I worry about every twinge) and I'm 7wks 6days today. For the past 48 hours or so I've had lower abdominal/ pelvic discomfort - worse on the left side - sort of feels like a constant menstrual cramp but a little sharpness to the ache. Seems to get a little better in certain positions and is not preventing me from falling sleep. No bleeding at all. Had an US one week ago today where we saw the heartbeat. Anyone else had this constant annoying discomfort?  What was the outcome?
