I’m 13 and my last period was 11 or 12

Patient: I’m 13 and my last period was 11 or 12 days ago. Yesterday and today I have had period like pains and cramping. They aren’t severe, but noticeable. I’m not sexually active or anything. I’ve noticed a little bleeding also, which made me worry. It’s not a lot just whenever I use the bathroom and wipe there seems to be a little blood. I was wondering if this means anything, or should I be worried? I haven’t told my parents and I have not been to a doctor either. Thanks.

Symptoms: Spotting of blood
None-light period like pains/cramps
