anyone else??

Sarah

so last week at my 20 week (exactly 20 weeks) ultrasound appointment to find out the gender I was told by doctors that I am measuring at 18 weeks and 5 days... my due date is March 15th 2018 but with how baby is measuring due date would be March 24th but since it's so close to my original due date they are not changing the due date... MY husband is worried how small baby is for how far I should be. Anyone have this happen?
