Any tips on moving on after the arrival of AF

This sounds so silly, but I guess everyone needs some help from time to time!!!

We have been TTC for a year and I have a host of medical problems that mean I have had to come off many of my pain meds during this time. I felt so sure I was pregnant this month, like I just knew... and so AF turning up early has really hit me hard, even my hubby thought I was. Any tips to get me over this bump in the road, as I feel like crying whenever I stop and think!
