ovulating super early??

Ka

So my cycles are typically 32-34 days long, I normally hit peak ovulation on cycle day 15, every month, it's like clock work. Well I started my opk's a little early this month for whatever reason and I'm on cd11 and I got high fertility this morning which was shocking to me and I just did another one this evening and I'm at peak fertility?!?! is this normal to ovulate early or what is going on? Also I use clear blue advanced opk in case anyone is wondering!
