Should I go to the doctor??

About a week ago I noticed that my discharge was happening a lot more frequently and it was more watery than usual. A few days after that, I noticed a very strong smell from my discharge (not fishy though). It's a little itchy down there now and every now and then (not every time) it kind of burns when I pee just the tiniest bit. I'm so scared of what it could be and I'm scared to tell my mom so I can go to the doctor. Any advice?
