Tilted uterus and ultrasound

Aly • Mommy to 🌈 👶🏻 born January 2017. MMC March 2016 👼🏻
Has anyone with a tilted uterus had an ultrasound that measured smaller than they should have been? I've read that this happens sometimes when you're really early on in your pregnancy. I had my first scan yesterday at 8w5d and only measured at about 6 weeks. Trying to convince myself that my baby is still hanging on! I go back in a week to see if there's been any growth.
