It’s too soon for implanting right ?

So I had a baby boy 8/9/20 I had sex either last sept 24th or 25 it’s was midnight he pulled out but My faith in that pull out was weak because it seemed kinda half way through well on Tuesday I had a little Light pinkish bleeding but that was after having sex the night before it wasn’t rough enough to make Me bleed but hey I just had a baby so who know 🤷🏾‍♀️ I’m freaking out a tad because I thought the bleeding would be the start of a period and so far I don’t even have so much as a drop of blood all day and the bleeding Tuesday was very light and little but I wouldn’t be implanting 4-5 days later right ?
