Need Advice! 33 Weeks 🤰🏻

Shirley • Married 💍 Third Time Mom♥️ 1st Baby born 01-25-2018 👧🏻 2nd Baby born 06/24/2020; 3rd Baby - Miscarriage; 4th Baby - Medical Termination diagnosis of Turner’s Syndrome

Hey Mommas! I was just at my 33 Week Appt. My baby is weighing 4 lbs 4 oz. At my last appointment 3 weeks ago she was 3lbs 5 oz. They're going to do another ultrasound in 2 weeks because she was in the 53rd percentile last appt & now she's measuring at a 33rd percentile. It's fluctuating so they want to make sure it'll go back up because if not I have to get monitored twice a week. Has this happened to anyone? Should I be worried?
