🚨HELP HELP SOS🚨

Okay ladies i need help! Im anxious and dont know what to think. So, this a screenshot of my ovulation and the days that i had sex. Glow is normally ON POINT with my period estimations. So, today when i got home, i went to the restroom to pee. When i wiped i saw this dark brown, pinkish color, also with a mixture of white discharge im guessing? Or could it be implantation bleeding? My cycle is 4 days away. What do you guys think?
