Help please

Glow has my fertile window being the 4th - 10th. With the 8th being the highest chance of getting pregnant. My husband and I BD on the 4th, 5th, 7th, and 8th. I didn't not get my positive opk until the 8th though. It's the 9th today and we are both just absolutely exhausted. Is it okay to take the night off even though tomorrow is my last day in my fertile window or is this gonna significantly effect my chances of getting pregnant?
