Help finding placenta in photo

Amy • Biz owner, was a teen mom to a now 18 year old 🩷. Baby #2 was a 5 week NICU warrior born @ 34 weeks in August 2020 💙. Baby #3 born at 33+2 in June 2023, currently in NICU 🩷

I'm 16 weeks now, this was done at 6 weeks and was an abdominal scan. Can anyone help me identify where the CV/placenta is forming? I can't differentiate between placenta and the rest of the background. TIA!
