mid cycle spotting

Hi ladies so my period started on the 21st June and went for around 6 days, my fertile window (according to glow) started on the 8th july and I had pink/brown spotting when i wipe on the 10th that lasted for a few days. I also took an ovulation test (clearblue advanced) and had the flashing smiley face with means high fertility (havent got hit the peak smiley face yet.) This is around our 6month TTC and i havemt got the spotting before, wondering if you ladies would know what this could be? Also i was taking provera to help me with my periods as they are irregular... 😊 thank you and sending baby dust to everyone 🌸🦄
