4 &5 dpo, light bleeding, achy breast. I need help

Priscilla

I had Saline Infusion Sonohysterogram on the 18th and it was diagnosed again, i had PCOS ovaries so i don't ovulate every month, but this month , my egg will mature in 2 days. This made a difference meaning my body doesn't follow when the app says i am ovulating or even using opk . Now 4 and 5 dpo now, and I had light bleeding, intense achy breast , nipple burns. I don't want to over think this but could this be a good sign? 9 days more to AF!!
