For the ladies that have been trying for years

I have a question for you ladies that have been ttc for years. I'm the one with fertility issues and although there's a possibility of pregnancy for me its a very VERY low percentage and if it does happen the percentage of it being a sticky baby is even lower percentage. Anyway I don't know if I still should track ovulation with opks? If you've been ttc for years do you still track?
