I'm terrified of a bfn but I think it may be our month!

Lots of nausea and some vomiting. And I've been having clear discharge like ewcm the past two days. It's occasionally tinged with some brown. SUPER tired. 
AF is due in two days and I will be so let down if this really isn't it... TTC #2. 
Any of you ladies have similar symptoms and end up getting a BFP? Trying to keep my spirits up.  😄
