OPK 2days before my period

Idk if this it’s the brand or not but my friend who literally takes medicine to ovulate has peed on these too and the lines are always so faint i read where getting a positive opk before a period or missed AF is a good sign??? I’m not sure but it’s literally crazy i ordered a better brand tonight but even when i know for sure i ovulate these test never get dark not even the control line 🙃 but they’re both darker than what they normally would be! Soooooo is that a sign of early pregnancy ? Took a pregnancy test at 10dpo and it was a faint positive just wondering lol no pms symptoms other than my hip is burning in the joint as with my first pregnancy
