BFN at 14 dpo

Hey ladies,
I'm feeling so discouraged after my BFN this morning. This is our 5th month of TTC after MC. I know there's still a chance before AF shows, but I'm exhausted from the repeated disappointment, and just want to move on with my life. I feel more and more desperate as 2 of my close friends have gotten pregnant in the last several months. They were my support system, and now I can't talk to them without feeling jealous and terrible about myself. 
Does anyone have any suggestions for staying positive after months of ttc after mc?
