Light bleed after sex?

So I've been sexually active for a while now so it's not like I broke my virginity or anything. I've had rougher sex with my partner that didn't leave me bleeding at all.

So a few nights back, we did the deed, it was short and sweet. Then the next morning I went to the loo and when I wiped, there was some pinkish blood along with my discharge and what was left of the semen (tmi, I know but we're trying for a baby so hey-ho)

What do you guys reckon it is? Surely implantation doesn't happen that fast 😂😂😂
