bleeding after cervix check

I check my cervix every day, trying to learn more about my body and this month it is different. It's raised higher and firmer which leads me to believe this could be my month! My period isn't due for one week so I haven't tested yet. Anyways, when checking my cervix today, I came out with a little blood on my finger. Barely any. I've checked a bunch of times since then and haven't gotten any more. Do you think this could be my period coming early or is it possible to bleed from opening my cervix by accident? I've never been early and I've never spotted in my life
