I will call my dr but pls help

I had a transvaginal ultrasound on 11/13 to get diagnosed with pcos which I have. I am not pregnant and I was on my period when I had the ultrasound. I am still having medium flow and pretty intense cramping 3 days later (period should have ended 2 days ago). Is it possible that the procedure caused old blood to get released?

Please comment with any tips or advice.
