OPK POSITIVE ON THE 2...

Alston
Okay so I'm 7 - 8 Days DPO and I took and it looks negative also took an ovulation test because I heard if you're very early to take an ovulation test and if it showed up dark that's a possibility that you could be pregnant I have pictures 1 please explain it to me better because understanding why is my ovulation test so dark I know it's not a positive ovulation because I ovulated obviously on the 2nd like 7 - 8 days ago one give me some advice if they've gone through this
