Fertility 4 days before ovulation?

Hi,
​We've been TTC since July with no luck yet. I finally bought a ClearBlue Advanced ovulation test for this past cycle. My highly fertile days were 9/5-9/9, and my peak days were 9/10 & 9/11. We had unprotected sex 9/5 & 9/6. I did notice clear, runny cervical mucus on 9/5. I had intense ovulation cramps on my lower left side on 9/10 and more lower abdominal cramping on 9/12. I'm praying for a BFP in two weeks, but am just wondering if we have a chance since we only DTD twice at the beginning of my fertile window. Thank you in advance for any input! :-)
