Vaginal discharge - is this normal?

Hi everyone 😊

Ive recently (last 2 weeks or so) been getting a looot more discharge than normal and its changed from whitish yellow to this brownish colour. Everytime i go to pee (about every hour) i wipe off big pieces like this and ive never had them before. My period is still a bit more than a week away and im quite regular so i dont think its that. As regards to smell, the discharge itself doesnt smell but the fact that my panties are always soaked with discharge is making them smell a little.

Btw, im 18 and still a virgin so it cant be an STD/I

Should i go and check it out? Ive never been to a gynecologist before but as i mentioned im not sexually active and never had any of these problems before. Thanks so much for your help and i hope youre having a good day xxx
