Implantion Bleeding or Ovulation? WARNING GRAPHIC PICTURE

Almost two weeks ago I had sex, on here it said that my ovulation would be two days away. I normally cramp during ovulation and bleed a little bit I can’t remember that happening when I was ovulating. We didn’t use a condom and withdrew, but I am on birth control. My cycle is around 29 days long and it said that I should’ve ovulated on those days. I have been cramping a little for the past couple days. Normally when I ovulate my spotting is dark and kinda medium. But today I looked when I wiped and this is what I saw... Should I take a test or just wait? Maybe I’m just being nervous. Have any thoughts?
