At my 20 week appointment I was told I would need to come back at 24 weeks to recheck the babys size. Was a little small. I went back in today and was told everything was fine but the baby is small and they want me to come back in another 2 weeks to recheck the babys head size. They took blood work to test for a virus. I was so mind blown about the entire thing I didnt even catch what they were testing. Depending on what the next ultrasound shows they may recommend an amniocentesis. Has anyone else had anything similar. I've left a message for my OB to get her thoughts just wanted some others.
