Ttc after loosing our baby girl at 17weeks

We lost our baby girl at 17weeks. I had to have a D&E.; Everything went as well as that can go and my doctor told us to wait 1 cycle until we try for another baby. We are so desperate to be pregnant again an I just finished my first period today since my d&e.; We are going to try to get pregnant during my fertile window and I find myself trying plan out every little detail so hopefully we will get pregnant. Did anyone else feel like this? And did anyone else get pregnant right away? Tips? I need some reassurance!
