Has anyone had a super positive OPK like this? I had a few of one brand left over and I wanted to use them up so I could use all the same of a different brand next month. This was yesterday's and before:

Today the line was even darker and showed up super fast. I use several methods combined to predict O and confirmed it happened on the 7th/8th, and my period is not due until the 22nd.

Does anyone have any thoughts or experience like this? I know it's too early for a HPT, and that OPK's aren't reliable for that either. And I know a second LH surge happens before AF, but it should be only a couple days before, not a week plus. So I'm super confused. 💁
