Peak to High fertility on OPKs? -- PLEASE HELP

Micro
I don't have PCOS and I'm using ClearBlue digital advance OPKs. This month I had 6 days peak (solid smiley face) +OPKs, and on day 7, I had a high (flashing smiley face) +opk. Has this happened to anyone else? I also used Internet cheapies to confirm if I was actually ovulating and they were all positive too. This has never happened to me before and I'm really confused. Anyone have this happen too?
