Mrs Mac, I had a light bleed at 14dpo (pink) and 15dpo (brown) with DD and she was fine. Bleeding/spotting seems to be more common with IVF cycles, but not sure why. If you don't have any pain to go with it, chances are it's fine. Just let your Dr know tomorrow...

FX for you too Andie. I hope your BFP sticks around for many more months.
