Don't know what to think

Ashlee • Little Miss Mini Me coming September '19

I went to the hospital on Monday because I was experiencing severe cramps. I spent 5 hours there (being dismissed as 'panicky') only to be told that my pregnancy is only measuring at 5 weeks, when I thought I should be getting close to 8 weeks today. I'm so frustrated. They didn't tell me what was wrong, only that I needed to schedule a follow-up ultrasound in a week to be sure that the baby is forming. I'm so sad and scared and frustrated.
