Nub theory guesses for fun?

Any gender guesses? Scan at 13 weeks exactly. Have three girls so far but sadly only one earth side. Hoping with every ounce of me this pregnancy works out 🤞🥹✨️ So excited 🤩🤩

Hard to say. Could be either but I am leaning towards boy. Fingers crossed that all goes well.
