Early reassurance scan

Went for a private early reassurance scan at 8 weeks 6 days. The sonographer once measured me at 6 weeks 2 days. Now I’m panicking.

We couldn’t see much on the scan, she did say a tiny line was the baby which looked like a flicker. My last period date was the 15th October hence why I thought I was almost 9 weeks. So disheartened now, but I’m trying to be mindful I could of ovulated late ect. I only had my midwife booking in appointment last Sunday and had bloods took.

Just the whole experience felt abit off, told me to come back in 2 weeks and pay another £45. Felt like they just wanted more money.

Has anyone else experienced this?
