Can this be implantation bleeding?

Hi, so please don’t judge we aren’t actively trying for another baby but if we have an oops baby we are good with that as well. Also not looking for birth control suggestions or advices.💛

So I’m currently 4 months postpartum (which why we aren’t actively trying) I had my period since I was 2 months postpartum. My last period was from 13 to 20th of this month (December).

Between the 20th and today we’ve had sex just once (Dec 23 or 24) because our busy schedule. Today like 2 h ago i wiped and it was faint pink spotting like egg whites. My peel ovulation day was the27 (cycle day14) Now, I’ve never had or noticed implantation bleeding in my previous pregnancies but I’m also not having any of my normal period symptoms. Can implantation happen 2 days after your ovulation day or am I being paranoid? Thank you!
