2 periods in a month?!?!

Hey girls! This is very concerning for me. I had my period dec.21 and lasted 5-6 days 2 weeks later when I was ovulating or supposed to ovulate I started bleeding again like a period. That lasted 7 days. Now 2 weeks later I started to feel as if my period was coming. This time symptoms are different. Real BAD lower backaches. Intense cramping and a lot of discharge like right before I get my period. Twinges and pulling around my belly button. The thing is I havent gotten my period. I am 31 so maybe my body is changing.

Has anyone else felt this way before??

Also adding that around the time that I had those intense backaches and cramping I check with toilet paper inside to see if there was any blood. And it was barely anything on it. Maybe like a slight barely visible tint of brown.
