Baby’s head measuring about 2 weeks behind


Hey everyone! I was just wondering if anyone has had a baby that measured small in the noggin. I am 31 weeks and everything else is measuring fine at 41st percentile but her head is measuring only about 29 ish weeks. I made the mistake of googling it and all I saw was microcephaly. Can anyone who has had the same news reassure this nervous mommy? I got scheduled to go to a high risk OB on Monday to make sure everything is okay but I’m anxious! Thank you!!
