Implantation Bleeding?!?!

hey yall- this my first time coming on here & posting but I really need some advice from women with experience. I finished my AF 3/6, had unprotected sex on 3/7 & began spotting/light bleeding yesterday, 3/18. Today the consistency increased & is only when I wipe, not enough to appear on a pad or my underwear. Image was taken today, 3/19. Can someone help/give some input?
