6 weeks 3 days ultrasound?

Morgan

I had an ultrasound done last night at the ER because of really constant cramping. I haven’t been to the OB yet so the only date I have it based off when my last period was. I’ve seen other people’s ultrasounds at 6w 3 days and theirs don’t look exactly like mine. I was just wondering if this is normal for it to just be a bubble? We heard the heartbeat and everything and they said everything looked fine and healthy.
