I am really sorry for your loss
from what I have read and been told, since there is often bleeding and or spotting after a loss, that may or may not be AF, it is better to wait until you are sure you have started a new cycle...and it's better to wait until your body is healed and ready to be pregnant again. But I can't say 100%.....just adding what I have been told...I know all about those "magic" numbers for problems...
Last year I found out on my 38th b-day that I had lost my baby .
I am happy you found us here....its a great place !
take care!
