Bleeding... didn't mean to post here

I thought I was suppose to start my cycle yesterday but didn't . Glow updated and said I start on the 8th . Today is the 6th and I'm bleeding and cramping . Not like a normal period . NO GUSHY OR HEAVY FLOW OR BRIGHT RED . It's none coming out when I use bathroom . I don't know what it can be . It's not a normal period.
