withdrawal or implantation bleeding?

hi!

i stopped my pill midpack (wednesday) and already had my withdrawal bleed 3 days later (saturday). it was light and the color of the discharge was color red, like it was a menstrual bleed.

now, 2 weeks later, i had a bleed again, but this time it’s dark brown and its very light. i’m not sure what this is this time. i had unprotected sex the 2nd day (friday) i stopped the pill and not sure if the guy came inside (i dont recall). pls help :((( idk what to do!

this is the discharge now
