How likely is it to ovulate early?

Kerrie

My cycle is 35-36 days long I always get a positive on CD21 and ovulate CD22... today I got a tiny amount of EWCM followed by creamy so still not super fertile so I took a test and I know it's not positive... but it's quite dark and usually when I get this my positive is a few days away..: I'm not actually due to ovulate for another 8-9 days :/ on cd 13 ATM!
