Implantation?

My last cycle was January 12-20th. I just started having some very faint spotting, it's light pink and kind of mucous like? I had unprotected sex on the 21st and 22nd, he finished in me 3 times. I am on the pill, buuuut I was on it when I had my last one too. 😅

Could it be implantation bleeding? Or is it too soon?
