hearts broken. Ivf failed

Been a long 4 years trying to conceive naturally and didn't work. Finally took my first step and got treatment..Undergone the horrendous two week wait and a long cycle. Took me 22 days to get my eggs retrieved, and only one fertilized. Hoping it was my miracle baby, and it just didn't happen. Had negative hpt tests and severe back aches. Guess God has a better plan for me. Just feel at a loss.
