2 periods in one month?!

Alia

Hey ladies. My last period was on the 8th of Jan and for the last 2 days Ive been spotting but I’m starting to feel like I actually have my period because the blood is getting darker (still not dark enough to look like my period though, and no clots) and its starting to fall on my underwear. I’m not on any type of birth control nor am I taking medication, should I be worried? This has never happened to me before
