Please help me period 5 days early !!

So I got my period 5 days early, and it was lighter than it usually is. The color was the same it just was a lighter flow, but I still filled a super plus tampon (not as many in a day maybe 1-3/day) and it’s lasted 4 days. I had an ovarian cyst rupture back in November so could that be affecting it or could I be pregnant? Any advise is amazing. Thank you in advance
