Feeling blue

Jill
I've never posted on here before but I am feeling fed up. My husband and I have been ttv #1 for 7 months now and nothing. 
I thought I was on to something this month as I had really heightened sense of smell but I did a clear blue early pregnancy test 10dpo and nothing. Af should be here on Sunday. 
Has anyone had experience of conceiving after 7 months? I really need to hear that right now. I'm feeling really dejected.
