Measuring Two Weeks Behind

Ebs

Have anyone ever experienced your baby measuring two weeks behind suddenly? I was at the ER all day Easter for severe stomach pains. They did an ultrasound of my gallbladder and of the baby. Both were fine, but they noted that the baby was measuring more at 15 weeks than 17 weeks. My OB is out of town and can't see me for a follow-up until the 19th. Now I'm nail-biting.
