Help ease my mind please

10 weeks and worried baby wont have a heartbeat in 2 weeks at the scan.

I have alot of the same symptoms i had at later stage of my first pregnancy.

I asked in one of my birth month group but they're all American and just keep saying if you haven't seen the heart beat yet baby probably doesn't have one 😔

I wasnt at all worried about my 1st but i only found out 3 weeks before i had a scan and was dated at 12+3

Ive already known about this baby for 6 weeks and 2 days 🙈 and I guess the long wait has me scared.
