Vagina smells

I'm on my period and I recently got told my someone that my vagina smelt so gross (how he found that was a joke as we were out ) they said it has never been that bad and this was just odd , I don't know if it's the fact that I'm on my period or something else but I need it to go because it does smell for me too and it's making me feel sick to my stomach smelling it I just want to get the problem fixed
