Early ovulation???!

Had Late period in Jan, and af came jan 29-feb 3. Had sex with hubby 2/8 and noticed EWCM afterwards. Glow( I know is an estimate) says O day should be 2/14...is it possible I O on 2/8? Been testing with opk since 2/10 and they just keep getting lighter

These are 2/10, 2/11, 2/12

2/8
