Confused!!

Arielle
I switched obgyn's when i was 19 weeks and 6 days.. My new ob doctor said I'm not able to get another ultrasound done.. The last one I had was when I found out the gender which was 19 weeks 6 days.. I'm just so confused cause I thought I was supposed to get more ultrasounds done.. Anybody else ultrasounds stop early? O and I'm 27-5 today due date supposed to be July 17th
