PLEASE HELP

I can not tell what is going on with me and my period. Me and my boyfriend use a condom everytime. i have been feeling very tired and nauseous lately and was supposed to get my period a few day’s ago. We use a condom so i don’t know how pregnancy could even be a possibility. i’m getting weird spotting and i suspect i maybe could have BV, which can cause that. I don’t know where my period is !!! i feel super ill and don’t know what to do. please help
