Ttc for 10 years 😥

So my husband and I have been ttc for 10 years. This is the 1st month I am doing opk. I keep getting positives and I'm not sure thats normal? So there's the calendar of when we BD and it's says my highest chance was the 19th. And also we have been using preseed. What do you think? Is it possible this could be our month? Any success stories with a similar situation?
