I’m six weeks today (judging from LMP, but I have long cycles, 36 days). I went for an ultrasound at my gyn today and all that is there is a small gestational sac, nothing else. We are waiting one week, getting another scan, and then making a decision from there? I had a scan last Friday too at the ER (due to cramping) and it was again, a small, empty sac. Did anyone have a similar experience and see something the next scan?
