What do you think our chances are this month?

We've been TTC for six months. I didn't start tracking bbt and taking Opk until month 5. I realized I waited to long to start them and missed ovulation. So this month I tried a new Opk brand and continued with bbt. 
I got a positive Opk on April 28.
Bbt marked ovulation on April 29.
We BD on April 25, 26, 28, 29 but then not again until may 3. Used preseed on 28/29.
My fingers are crossed this is my month. I'm about 6dpo and had a dip in temp today.
