4th day of positive OPK's

Nichole
What gives? I had a positive 3 days ago and have had a positive(2x a day) every day since. I don't temp unfortunately and I do not have any other O symtpoms. I'm worried that I haven't ovulated, or that I won't this cycle. I'm on CD17, which is super late for me to ovulate in the past. Any experience?
