Weird Period - Help?!

I am so confused... so I am 3 weeks away from my next period and suddenly out of nowhere I go to the toilet today and what do I see?! 🔴

I also have light cramping. It seems too heavy for implantation bleeding but my period is 3 weeks away and it’s always been like that.

I did only just start my pill and by that I mean I took one and forgot to take it the last few days... maybe that is what it is?

Anyone have any ideas or personal experience?! Much appreciated x
