2nd period within a month... please help me understand

Samantha • SammyF.ckinPoppins Mommy of two but I'm rh negative so they are negative in this world

Alright my period is almost always on point persily. So this is very unusual and raises concern to me..

These are the current way my cycle is behaving..

This last one is my normal cycle prediction..

Any help or opinion from personal experience or anything else that can help me make sense of what's going on would be awesome.

To note.. I was incarcerated for 12 days surrounded by other females and I'm not typically around but one female at home..
