weird smell

hey girls, so i’ve noticed my vagina has a weird smell? it just started last night and still does this morning. i just got off my period but it’s not smelling normal? there is no itch or anything like that, and i don’t have any weird discharge. is something wrong or is this normal? i’m at the beach for vacation and i have been in the heat a lot. can this have something to do with it? please help!! i want to go home and have sex with my boy (haven’t seen him in a week and will be home saturday) what should i do??
