I was going to suggest that you take your temperature. I used OPK's but always cross referenced with the temp. I could sometimes get really long luteal phases.

Good luck!

It's possible, but unlikely. Are you using a digital with first morning urine?

To OP's question - yes, you can be pregnant with a negative test. My first pregnancy, I didn't test positive until well after the date of when I should have started my period. I also had implantation bleeding around the time I would have had a period - it was light, but enough that it confused me and I thought I might have had an actual period. The big tip-off for me was that I felt really, really tired. 2nd and 3rd pregnancies, also really late for positives (but I was expecting that after the first experience).

same thing happened to me as 20:28. my cycles were always 28-30 days. OPK positive on day 17, just like normal, but temps showed i didn't ovulate. this freaked me out and i thought maybe i wasn't ovulating at all -- this was my first month temping. kept using OPK and ended up ovulating on day 33 or so -- after i should have gotten my period. i ended up pregnant, but if i hadn't been, my period would have come about day 44. because it was my first month temping, i thought there was a possibility i had done it wrong, and did a pregnancy test every morning starting on day 30. didn't turn positive until about cycle day 45. so period was very, very late based on average cycle length, but actually not all that late based on average luteal phase.
