24 week check up... concerned!?

Allie
Went in for my 24 week check today, She measured my belly before doing the Doppler and then didn't say anything else in regards to the measuring except she wanted to do ultrasound next time for growth and fluid levels since my SVT (super ventricular tachycardia) - even though haven't had any episodes this pregnancy. Also being tested for regular glucose test, no biggie on that...If I was measuring a small belly, wouldn't she have told me? Now I'm freaking out!
