E.R.?

I don't know what to do. I have a fever, I've been bleeding off and on for over a month (birth control pills), I feel nauseous very bad, can't see straight, I've eaten so it's not that. I'm over heated even though wearing shorts and tank top. My body is like vibrating or twitching, I have a pain in my head, my BF wants me to go to the ER but I don't know what to do. Should I? I feel very very sick but feel like my mother won't take me.
