Quoting ℳizz ℊiz. :" Also I push slightly on the spot now, (not hard. As gentle as she was sliding over the spot. So just slight pressure.) and I feel NOTHING anymore. The weird feeling is gone."
I'm thinking it probably was just one of the babies' limbs especially since you said you can push on it now without it hurting. I wouldn't worry too much although I know it's hard to do! My ultrasounds didn't exactly hurt but I do know sometimes when they would press up against my ribs, it would be a shooting pain. What you described though sounds like what I experienced(not during my ultrasound) but my girls would move and they would, not even joking....rake their arm across my stomach. You could literally see it as it happened and felt their elbows. Lol. It was odd. That would hurt and kinda sounds like what happened with you when the tech pressed down against your stomach.
