TTC a baby girl

Hello everyone I need advice on ttc a girl. My husband and I have two little boys and we want a girl without having tons of kids (lol) I had the nexplanon implant removed a few days ago and I'm not sure what's our next step in conceiving as I have read up on shettles method and other methods. My last cycle while having the implant lasted from august 5th to September 14th with on and off spotting. Once I had my implant removed (September 15th) it immediately stopped. Advice?
