Clearblue Advanced OPKs are freaking me out...

So, I've made a couple posts about this, without really getting much of an answer...

I've been testing with Clearblue Advanced OPKs since cd11. I'm now at cd19 and I have tested high for the past 8 days. This definitely isn't normal for me, usually I have high fertility for 2-3 days and then I ovulate. I have yet to ovulate. I've attached my bbt chart, but I'm new at temping, so I don't even know what it means. I'm not on medication, but I have been taking vitex and serrapeptase(sp?). My body is usually very normal, but this is really wild. Not freaking out, just very curious! Any thoughts, ladies?
