So my fertility dr has been doing vaginal ultrasounds since I was 6 weeks.... last week I went in @ 8w & 3days heart beat was 176 & I was measuring ON Time like I usually am.... I go to my OBGYN because I will be released from my fertility dr on the 16th & she did a quick abdominal ultrasound on the super small machine ( not even the regular sized machines) I’m suppose to be 9 weeks & 3 days today and I’m measuring 8 weeks & 6 days & the heart beat was 150?

Is this normal? I feel like she rushed it & I know for a fact every vaginal ultrasound has been on time every time. Is there a difference between ultrasounds? I’m so confused and it’s worrying me.

I have my last appointment w my fertility dr & I’m sure I’ll be measuring on time with them ( which next Friday I’ll be 10 weeks & 3 day )
