Is it normal to have bleeding 12 days before my period?

Rebecca

I had light spotting yesterday and then no spotting this morning and then this afternoon I had spotting then I noticed that I was bleeding like it would be when I have my period usually. My period isn’t due for like 12 more days at all.

I know my husband and I haven’t been sexually active lately and so I’m just wondering if I could be pregnant and not know it.

Is that even possible?
