In need of encouragement

Shanie
My husband and I have been TTC for 9 months. This past month my father died unexpectedly. It was very stressful, but we continued TTC. Now, I'm on day 42 of my cycle, 5 days past expected period with no signs it will start and 3 BFN. I'm becoming very discouraged. I feel there is no way I'm pregnant and I don't know what to do.
