OPK help

Danielle
Hey, I'm new to all this! 
I was due to come on my period 2 days ago, I think... as I have very irregular periods. I had all symptoms, felt like I was on my period but no period blood. Negative pregnancy tests
So today took a OPK and it shows a faint line. I know it's not positive but does this mean I'll be ovulating soon?
Thanks
