Cuts at my vag

so when I pee it sometimes burns the first second then goes away and when I wipe there's a tinnnnnny bit of blood stripe And I looked in the mirror  and there's these little cuts like at the opening of my vagina in between my vag and Anus but it's connected to my vag hole almost like its ripping 
almost like paper cuts 
I'm only 14 & I think I have a yeast infection but I'm just scared to tell my mom about the cuts
