Non viable pregnancy info? 7 weeks 5 days.

I should be 7 weeks and 5 days pregnant, NOTHING less. I have 36 day cycles and ovulate a little late. I had sex ONCE in September, so dating back is pretty easy to how far along I am. September 12 is the date I had sex.

I had an ultrasound yesterday and they scanned me at 6 weeks 2 days, which makes no possible sense based on the ONE TIME I had sex.

They said to come back in a week and a half to check on growth but based on the info they gave me, they’re not sure it’s a viable pregnancy.

I got my HGC drawn and was at over 77,000. We saw a heart flicker so it was there. I’ve been really upset and unsure what to think.

Any info on this?
