All you post birth control experts!

So Sunday was my first day of not starting a new pill pack. I have been testing with opk's since to see if I'll even ovulate this month (was on bc for 10 years and I'm 25) Today is cd8 and I had an almost positive. If I'm anything like most women, I'll probably get a positive opk tomorrow. Doesn't that seem really early that I'm ovulating cd9- especially after just stopping the pills? 
Also NO cm whatsoever! 🤔
