4 days of positive OPKs

Renee
Here are my OPKs. The thing is, I already 2 had positive OPKs on 6/30 and 7/1. At first I thought maybe I was having a late surge and didn't actually ovulate 12 days ago since last night I had a negative test. That still may be the case but I'm confused as to why my test was positive again this morning.  Took a hpt too and that was negative. Thoughts??
