Bleeding?

I recently just got my first vibrator. It’s just for the clit, so I haven’t inserted it but after every time I’ve used it for the past few days I lightly bleed, kinda like an extremely light period, it’s very little blood. I only bleed after for like an hour or two, but then nothing. I checked and I didn’t cut anything, so it’s definitely coming from my vagina. It doesn’t hurt but it’s just so strange and I’m not supposed to start my period for another 12 days. Just wanted opinions on it because it makes me nervous to even use it now.
