Help!!

So I’ve had my period already this month, and I had it for 2 weeks which is very strange considering I normally get it for 5-7 days. So my period finally finished the other week and yesterday when I woke up I had some blood and then again today I have woke up with the same thing. But my next period isn’t due until the start of next month, and considering I’ve already had it for 2 weeks this month I’m very concerned so I’m just wondering if anyone could help me figure out what’s happen

Thank you x
