Does this sound normal?

Re

I see my obgyn every 3 weeks is this normal? I have told her i had a miscarriage before so not sure if that is why. I'm kinda scared because i feel like something is wrong but she's not telling me just keeping a close eye on it. I heard some girls only getting like 2/3 ultrasounds through their whole pregnancy or going every month.

My appointments so far:

June 7- 4+5

June 28- 7+3

July 12- 9+3

August 2- 12+3

August 23- 15+3

Ultrasounds just because! ❤
