Baby measuring smaller - Need reassurance 😞

Sarah🌺 • 25, Married, 1st Pregnancy! 💘

I went in for my first ultrasound on Wednesday (Valentine’s Day 😍) and based on my last period, I should have been exactly 8 weeks. When the doctor measured she said I was exactly 7 weeks instead. She said it was nothing to be concerned about.. we did hear the baby’s heart beat - 133.

She wants me to come back for another ultrasound next week to measure the baby again before she officially changes the due date.

Is this normal?

First pregnancy, and everything is completely freaking me out 😩
