Does anyone else have any experience with these?? We got told at 22w he has on less than 1 cm. I have to go back in at 28 weeks for another ultrasound and I've been freaking out ever since... I've had downs and trisomy 18 testing and it all came back okay. All his other organs lok fine they said. I've done a little research but would like to hear from real ppl if possible... thank you.
