Clotting

So about a month ago I was diagnosed with a 2 cm complex cyst. I was told because it’s so small to come back in 4 weeks for a transvaginal ultrasound to see if it goes away or gets bigger. I went back recently and was told it’s gone but I have a simple cyst on my left ovary.. anyways then my period comes like three days late and starts clotting like this. I’m not sure if this has happened before but has anyone ever clotted like this before? Or could it be from the cyst maybe rupturing?
