Can you Please Ramzi for my Husband?

Keiki
Today was the best day ever! We got to see our baby for the first time ever and hear her or his little heartbeat! 👶🏻🦄 I should be 7 weeks and 2 days according to my LMP, but I have late
O and had four days in a row of + OPKs. Abdomenally, the baby measured at 7 weeks and 1 day. Transvaginally, the baby was 6 weeks and 4 days. Basically how my OPKs were - if I had ovulated during the first + I would be 7 weeks and 1 day and the last 6 weeks and 4 days. She said that they usually go by the transvaginal one as it's more accurate. Any thoughts? Also, my hubby is wondering if anyone can use the Ramzi method for sex prediction for our baby! Thank you!
I feel like I'm walking on a cloud! Happiness and health to all! 💚🌈
