Chance?

I had sex Friday, Sunday, and Wednesday (yesterday). I took an opk Sunday and it was close to positive with both lines being almost the same color. I figured that was my positive and we had sex. Yesterday I took an opk for sh!ts and giggles and had a BLAZING positive, test line was so much darker. So we had sex just in case.

Now I feel like an idiot for not testing Monday-Wednesday. I know they can stay positive for a few days so I'm worried maybe I ovulated Monday or Tuesday and we missed it. Did we miss ovulation? Or is there still a good chance I'll be pregnant?
