First IVF worked and thinking about a second baby what are my odds?

Alejandra • Male infertility had one egg retrieval, 1st FET was 2016 successful baby girl and second FET 2018 and currently pregnant with baby Boy! God is Good

Thank God my first IVF frozen transfer worked. I have a 8 month old healthy baby girl and I have a frozen embryo left and would like to try for it this fall. What are my odds that my transfer will work again? 🤔
