What do you think? X

I track my ovulation and test with ovu strips so today makes me 13dpo. Late period, I have cramps on and off, have had some pink discharge / spotting past couple of days but no period started, back ache, headaches, fatigue & sore boobs (however all relatable for me when expecting AF too) only thing not normal for me is the pink discharge I normally start AF quite heavy. I’ve taken a few FRER however negative. Should I rule out or possible to still get a bfp if AF doesn’t arrive. I thought FRER would have detected at 13dpo but new to this.. 😫
