How long should I be getting high OPKs?

I started testing with clear blue digital OPKs the day that Glow predicted my fertile window would begin (which was last Tuesday). That day and Wednesday I had low results, but Thursday,Friday, Saturday, Sunday,Monday, Tuesday and Wednesday (today) have all been high. Does this mean I’m not ovulating this month?

I’m due to get my period on Feb 17th and it is always very regular so I don’t think my period will be late.

I’m really just so frustrated with the process and want a baby so badly! I can’t believe there are people out there who can get pregnant by accident when it seems like so much work! Help!
