Ovulation bleeding iud?

H

So I just had a iud check at the clinic on friday. All was good with the strings and ultrasound. Today 3 days after I had some blood (red) mixed with discharge. My period is irregular with my iud but glow says that I could possibly be ovulating this week. The bleeding wasn’t heavy but enough to notice, could this be ovulation bleeding? I know I’ve had brown mixed with ewcm previously, but never actual blood mid cycle? Lmk how common it is!
