Can you help me figure this out?

I am trying to figure out when my period is due. I usually have a 28 day cycle. Every few months, my period is a day or two late.

I recently started using OPK's and this month got my on CD 17. Today is CD 29. When would you think I am due for AF? I am thinking Friday because that would be about 14DPO/CD 31. Am I right?

Also, I am freaking out a little because I always spot for 3-4 days before my period is due. This month- nothing. Not a single tiny bit of spotting.

I am driving myself crazy over here, I am crampy and feel like AF is coming but nothing yet. We've been trying for over a year, so I am afraid to hope.

If you got this far thank you!

Im no expert with this stuff, but its possible you would be due for AF on Fri. I would hold out and test on Friday if she does not appear. The no spotting thing is a good sign though!!!
