2 periods in the same month

Ma

So I started my period earlier this month and it was heavy, dark red, and had blood clots but only lasted 3 days. Then exactly 1 week and 5 days later I started my period again but it’s all dark brown throughout the whole period and I had dark brown blood before but only at the end or start of my period, never like this. I never had sex or did anything out of my routine, so I’m wondering if this is normal or is there something wrong?
