Scared for Ultrasound

Erica
Ugh I'm suppposibly 18 weeks pregnant and can't wait for my first ultrasound this Wednesday! I say I'm suppposibly because my doctors keep switching it up and when they went to measure the baby it was too small to determine length! Scared! Let me see my baby so I know he/she is okay and how far along I've come! Thanks for reading my vent.
