thoughts please!

So I'll keep this straight to the point and please let me know if this has happened to any one and what the outcome was😊. My cycles are always 25-29 days.. never shorter and never longer. 29 days had always been my max number of days. Trying to conceive for two years in December. We BD'ed during my most fertile days and when I got a positive opk and day after. I did ovulate about 2or 3 days later than usual, which has happened before but still have never had a cycle longer than 29 days. So according to me, my period was due Thursday 10/27, and according to glow, it was due today, 10/30. We'll no period to be found, just some brown discharge earlier, some cramping and headaches for a couple of days. Took clear blue digital this am and got a negative.... thoughts please! Thanks!
