Stop trying?

Hi ladies
Me and my DH have been TTC for 6 months now. My AFs have been irregular for the last 8 months but Ive still been using OPKs with each cycle getting positive LH surges. I'm losing my faith and have heard tons of stories about how they stopped trying and tracking and it just happened. What do you all think? Any advice or positive stories would help as well? Good luck to all and so much congratulations to all who've gotten that BFP :)
