Well, you're not too young. Your female parts are those of an adult female, or close enough as makes no difference. Your mom might feel that only women who are having sex should see a gyn, but 14-year-olds do see them.
You say you have been checked for BV, but it would be the biggest culprit for odor, that or a forgotten tampon. If you can't get to a gynecologist, you could re-book with your regular doctor and ask specifically to be swabbed to check for BV.
Good luck.
My mom doesn't think that I need to see a gynocologist. She thinks I'm too young, and I'm 14.
You might have bacteria vaginosis I had that too and I still have it so I don't what my problem is but I infection free but I get strong ododr for a couple of days after I have intercourse.
Ask your mom to book you with a gynecologist, preferably a female, and lay the whole thing out to her without your mom in the room or being embarrassed. Explain exactly what has been happening and ask for some unbiased discussion. Then listen to the doc. If she says you don't smell worse than any other female, then you probably need to accept it.
ps -- Not shaving is a good idea. If the bumps are terrible still, get some Listerine, the old-fashioned "original" kind, which has eucalyptus oil and probably menthol and other stuff, and dab with it on the bumps. It is a good skin healer.
