New to OPK and a little confused

I’m new to the early ovulation LH SURGE testing, I brought two different brands (one Walmart brand and the other target Digital brand) my last cycle was July 10-16, I waited up until July 18 to start testing, for few days I tested negative. Then I got my first positive July 25 in the morning but then when I tested that same day but at night (about 10ish at night) on both test it was negative. Me and my husband ended up still having sex but it was about 12:30-1ish in the morning so which would mean July 26. My question is would I still end up pregnant even after I tested the second time when it said Negative?
