5 day Transfer

Cara
Hello Ladies,
Advice plz as very worried.
On the 24th of Nov I had 2 embryos implanted. The doc said to test Dec 6th but being impatient I have tested today the 29th 5 days passed 5 day transfer BFN. I've been an emotional wreck. I have sore breast and cramps on and off..:::! So worried that on the 6th it will be utter disappointment. How should I cope? Would love to hear from you.
