ovulation confusing opk

Gemma
hi everyone I had a positive clearblue digital  that went to peak on cd10 1st day cd9 was low and they have been peak ever since i have never ovulated that early before and this will be #5 if we are lucky so not sure to count cd11 as ovulation like glow says or stick to cd15-17 like i usually have due to it being positive ever since
​what do people think xx
