Yea the sonographer was the head of the ER. I would think he would know what he was looking at on the ultrasound and wouldn’t have told me he seen it if he wasn’t a 100% sure. He literally said it was just one sac so just 1 baby and that it was too early to see anything else
I think some free fluid in the pelvis is super common in general. I had a bunch of random ultrasounds to look for cysts and monitor an endometrioma I had. I think all my ultrasound results mentioned free fluid in my pelvis. I wasn't pregnant at the time or anything. I think it's just a common thing.
I had an ER doc diagnose my gestational sack as a blood clot, that blood clot turns 4 tomorrow. I know it's really hard not to worry but if your HCG is that high and you have seen something on the ultrasound it's possible they were wrong.
