Help! Positive opks on CD 22

Hi ladies, so last week glow told me to take an opk and I thought it was positive then but out of curiosity I decided to take one yesterday because I've had really bad cramping and pain in my left ovary and the top picture were all the tests I took yesterday the first response has a very faint line and the dollar tree one on the bottom looks positive so I decided to test again today and they both look positive to me that is the darkest line I've gotten on the first reaponse opk. I'm trying to figure out why I keep on getting positives it's very frustrating as I don't know when I actually ovulated and is it normal to be so late in my cycle? Any thoughts would be appreciated.​
