Weird bleeding

Iesha

I am wondering if this has ever happened to anyone. Last night me and my husband had sex it was nothing too rough compared to our usual and he didn’t insert his fingers into me. Well when I went to the bathroom I wiped very very light pink blood which was bizarre to me. I’m 5/6DPO could this have been implantation bleeding ? I had some weird cramping for a little after. Any thoughts?
