Bloody Play

Well, I got kinda close with this guy I like last night it ended up with him eating me out and fingering me (note that we didn't even have sex!). When he came back from the bathroom and turned the light on we realized there was blood everywhere and by everywhere I mean everywhere- clothes pillow sheets duvet skin.. Bah. Of course we thought my period decided to give us an early surprise visit, however in the morning and during the whole day today there was no blood on my tampon. What happened? I feel slightly worried about this. Also thinking back the blood looked suspiciously clean (not the typical dark ish period red)..
