Today I had my first ultrasound with my obgyn 
18wks6days
The ultrasound tech started by going ahead and asking me if I wanted to know the sex , I told her I already knew but still was able to show me again 🙂
Anyways , well then she started measuring the brain , heart etc . what they normal do "if you've had and ultrasound before you know what I mean"  then she went back to the heart and started measuring again , and she stayed on it for about 5-10 minutes.. which was confusing and worrying me little bit . After she was done she told me to stay laying down and she'll be right back , 10 minutes later ANOTHER ultrasound tech came in and went straight to the heart during ultrasound... then I started getting scared , she didn't take but 10 seconds then she said okay looks great . Then left . My appointment was over . WHAT THE HECK ?!?! 
Sooooo does this mean somthing can be wrong ?!? Scared scared out my mind and been crying for hours... I called my dr but everyone has already left .. lady at front desk told me to calm down if something was "wrong"
They would of said something then & there .. which I believe it's a lie. Only your dr would say something right????
