Need some advice! 🤔

Hello everyone,
I am a newly pregnant mama and around 4 1/2 weeks pregnant! I wanted to know if there are places for women to go get ultrasounds done without an OBGYN or doctor referral? I'm going to be going on a plane into weeks and I want to make sure that everything looks fine prior to leaving. My doctors typically don't do ultrasounds until after eight weeks and by then I will be away on vacation! 
What should I be googling? And are there such places?
