So upset I won't have an ultrasound til 20 weeks!

So I'm 11 weeks, I had an ultrasound early at 8 weeks due to previous misscarraige and now my next uktrasound isn't til 20 weeks! At 8 eel the ultrasound was just a blob. I see everyone on here posting their 9-12 weeks and can see baby clearly! I'm going to have to pay for anprovatenscan somewhere!
