Trying to stay positive!!

So my partner and I have been trying now for almost 12 months solid. I miss carried last year in June, but still nothing. Everything is starting to get very stressful and upsetting as we still haven't had luck so being positive is proving difficult. This month we buckled down on my fertile days - now experiencing extremely sore nipples (sorry for details) usually this doesn't last for longer than a week and it has now. Secretly crossing all fingers and toes that AF doesn't show next week..
