I'm hopeful for you!
I think this month our cycles are quite the same only we are 2 days apart from each other. If I am right about my O time then I would be having a 29-30 day cycle and I'm on day 27!
If I were you I would wait a few more days. See what happens over the weekend and if no AF by Sunday or Monday then take a test!
i think you should wait a few more days, i've been ttc for 25 months with no luck and i get the brown spotting up to 5 days before AF is due, this might just be a late month. I hope you get your BFP anyway best of luck!!
