TMI ALERT

Ok I'm sorry to get gross. I am ttc and my period is due tomorrow. I took a pregnancy test at 9 do and it was negative. This past week I've been very gaggy in the morning. Like I don't want to talk because I feel if I open my mouth I'll puke. My cheeks are rosy in the morning... and I'm tired all day. I havent thought too much into it because its flu season. But the strangest thing started today.... my lady bits smell AWFUL. I showered this morning and by 2 pm it was just this terrible smell I can't really describe. I'd say it's a mix between .... acidic and sour. Like rotten onions? It's honestly terrible. My discharge is light but I'm very sweaty down there. What do you think
