White discharge help

Ok so I’m 16 and I usually have some white discharge but never like this. I was wiping after peeing when I noticed a little goey ball, it didn’t hurt and it didn’t smell like anything. I have an irregular period and I’m a virgin, I was at work so I was walking in the hot sun all day, I say this because maybe that has something to do with it???? Please if you know what this might be I’d appreciate it so much to know I’m okay or if I need to get something checked out THANK YOU
