Pregnant?

so this would be my second baby, if I am pregnant. I wanted to start out that I was in a little bit of denial because I track my period and avoid having sex on my fertile days and 48 hours after. We had sex 7 days after my expected ovulation date, and I got the results of these 2 tests (shown below). The pink dye test was stored in my bathroom for awhile before I used it and it showed a positive line, so I then ran to the store and bought the blue line test. I’m confused as to how I got pregnant 7 days after I ovulated, with my periods being 100% regular/ on time. Have any other mamas gotten pregnant after ovulation though you have regular periods?
