Gender in Ultrasound (Ob Sono told that its Probably Female, May pinakita din siya saking 3 lines )

Good day po.. Mayroon po ba ditong maalam sa pagtingin ng gender ni baby using ultrasound.. This was taken yesterday (18weeks) Me and husband already have 3 boys and this is our last na since nagpavasectomy na si husband. Hoping and praying na ito na sana yung baby girl namin🥺💓
