bleed during sex?

I usually bleed during rough or hard sex .I dont know why or how I do but it happens all the time. Well this time around I am two days late on period hoping I am prego and I bled. When i went to the restroom to check if I was on my period it barely was visible when I wiped it was like on orange pink nothing in the toilet. This morning when I went to check again there was no period or blood. I need some opinions was it implantation bleed or was it just that bleed during sex? Thanks for any help you can give!
