Vagina smelling

Ashley

I know it’s common to have a smell. However sometimes I’ll be sitting with a friend and he says it smells like fish. I would go to the bathroom and smell it, this happens when I get off my period also. I haven’t been sexually active and haven’t had time to go in for a test, going to when I get back to school. So my question is it common to have a lingering smell? I feel really conscious about it because I feel like it’s obvious it’s me lol
