I had an early scan today measuring around generational age around 6 weeks, measuring 5-6 weeks.. the lady originally said I was 6 weeks then changed it to 5-6 when she could see yolk sac but couldn’t see embryo

This was a normal scan not vaginal

They seemed so chill about it as everything else looked normal..

I’m very anxious though. My hcg levels weren’t checked but I have my first midwife app next week and a scan again in 2 weeks

Anyone else had something similar??

Or something that will put my mind at rest ?
