Earliest ultrasound???

P

I can’t get an appointment for another month! I’ve seen my PCP to have my pregnancy confirmed but the OB doesn’t have any open slots for ultrasound. It’s my first pregnancy, I have PCOS and endo, and twins run in my family so there’s a number of reasons why I want one ASAP.

What’s the earliest everyone had their first ultrasound? I found a clinic that will give me one for free without a referral but I don’t want to go too soon. Thanks!
