Good chance? Or impatient?

We've been trying for 9 months to get pregnant. This cycle I started using ovulation tests. I ovulated on CD22 last Monday. We had sex on the Saturday before and on Monday itself. Since ovulating, I've had very sore breasts and constant cramping in my right ovary. I always thought I ovulated somewhere in the middle of my cycle, so maybe I had sex on the wrong days all those other months—I never knew my ovulation was so late. My cycles have been quite irregular for the last 5 months, ranging from 24-36 days. But this time I'm sure we had sex on the right day. I know it's pretty early since I'm on day 5 after ovulation, but is there a chance I could be pregnant? I'm mainly wondering because of all these symptoms; I thought ovulation pain usually shouldn't last longer than 2 days. Has anyone experienced this? Did anyone end up testing positive?
