{{{{{AF vibes}}}}} - FYI, it usually takes me 4-6 days after stopping Provera for TBAF to show. I'm sure she's on her way!
ETA - the first time I took it, AF was super light - no more than heavy spotting for 3 days and that was it - so you may not get a full flow. Not sure what your plan is but if you are going for cycle day 3 testing, start counting at the first day of spotting.
