Does 10 weeks seem late for first prenatal visit?

I got a blood test confirming that I am pregnant on Monday and my GP gave me a referral to an OB. I called them and they said to come in at 8-10week but I’ll be overseas for week 8&9 so booked for week 10. I feel like this is a long time to wait to confirm things are progressing - should I try finding an OB that will see me at week 7? Is there any harm in having a u/s at both week 7 and again at week 10? Thanks ladies !!
