V.K.
Never ever ever... EVER... Look on the internet for stuff like this.
At my 20 week ultrasound the tech noted that my son looked like he was growing asymmetrically. My Dr told me that the tech had noted this, did not seem concerned, and we pretty much moved on without further discussion. Well the next day I got curious as to what that meant and googled it. Dear God!!! Within 5 minutes I was 100% positive that my baby wasn't going to make it and 80% sure that I was also going to die. I was a crying blubbering frantic mess!
I called my doctor in tears and she assured that it was nothing to be concerned about, but she set me up with a Dr at the university who did a 3D ultrasound. I also had 1 regular ultrasound every other week for the rest of my pregnancy.
Everything turned out fine!
