Tips on trying to move on...

Got my AF yesterday after having a faint positive and being three days late. This one has really been a killer for me. I'm struggling moving forward and readjusting my expectations. I just don't know what I can do differently. I'm on month 8 which I know is pennies compared to some of you but I could really use help with strategies of letting go. Everyone says to do it but I don't know how. We are trying for #2 and I desperately just want one more. Thanks for the advice.
