2 periods then no period?

Kam

I had my son on 6/18, got my first period on 7/31. Thought it was my first but it was light & only lasted 4 days. Got a 2nd period on 8/16 and lasted for 10 days! 😱 It was due 9/15 & hasn’t come yet but I’m not having any symptoms either, besides sore boobs. Is this normal? Could it just be my hormones? Stressing myself out & about to go buy a damn test but hopeful it will come anytime now. 😩
