FET transfer

I am 4 months pp and had an amazing baby boy via IVF in July. Had a lot of issues TTC pre IVF. I have unexplained infertility, had a miscarriage, found out I had a uterine septum that needed to be corrected. Tried Clomid for 4 months that made me feel like a raving lunatic. The Drs talked about IUI and said it was probably a waste of time. I was 37 at the time and felt like I needed to hurry up. We decided to go straight to IVF and was so lucky on the first attempt. Had a wonderful pregnancy and had to have a c section in the end as baby was breach. Now I am going to be prepping for our FET next month for the transfer in Jan! Very excited and fingers crossed a baby brother or sister happens just as easily next time around. We only have 1 frozen embryo left which makes me nervous but staying positive and thinking good thoughts. They will be very close in age but 2 babies before I'm 40 is my hope, however, gearing up for complete chaos if this goes to plan. 2 under 2? Am I crazy? Probably but it will be worth it in the end!heres a pic of my little man.
