blood in discharge

What does it mean when you have blood in your discharge but you don't have your period yet but it's coming soon. I'm worried cause this has never happened to me before. I haven't had sex it a while was thinking tonight I could have protected sex with a condom but I don't want him seeing a little blood by mistake when I'm not even on my period yet. I'm just worried it may happen again and embarrass me but after all he did pop my cherry awhile ago and I bled all over his whole bed haha. Maybe he's comfortable enough if I let him know before hand.
