Curious?

So I’m 9 weeks and we want to announce next week at 10 weeks but my obgyn won’t give me an ultrasound until 12 and I want to use them for our photos. There’s a pregnancy center here that will give a free first trimester ultrasound after your confirm your pregnancy. Is it wrong of me to use that resource and do it ? I have an appt Monday to take a test there and they said they’d schedule an ultrasound fairly quickly after that, so do you think I’d be able to get one before that Saturday?
