white clumps of mucus/discharge in toilet after peeling?

hi ladies. I don't know if this is the right place to post but I'm having some concerns. I just went to the bathroom and after finishing I noticed a clump of white mucus or discharge floating at the top and then like a ball of discharge at the bottom? I have no idea what it could be. It's not a mucus plug bc I'm not pregnant. could it be due to ovulating? bc I was due to ovulate this week and according to glow, today was my last day of ovulation and my last fertile window. or could it possibly be a UTI? I've had many UTI's and never experience mucus with them but I've heard that can be a symptom though I'm not having any pain peeing and the frequency hasn't changed. I am have pain by my kidney's though...
