It’s burns when I peed

Umm so I wasn’t supposed to get on my period till tomorrow but I got on early. So I was just at school less then 20 mins ago and I felt a strange stinging sensation going on where I pee at and I started walking weird cause it was stinging but not burning.

I get home and I noticed I came on my period while I was at school HORRIBLE THING EVER I bleed a lil through my pants but (I’m in my house now) I went to the bathroom and started to pee and it burned while peeing this is the first time this has ever happened and mind you IM ONLY 15 & STILL A VIRGIN I HAVENT BEEN TOUCHED OR NOTHING IT JUST STARTED TO BURN LIKE 20mins ago, it doesn’t burn now that I peed but it might start again and I just wanted to know if I should tell my mother and go to the doctor or wait a few days to see if the burning will come back or go away.
