Mel-- I heard you're supposed to wait until 5 days before AF, so I guess it would depend on when she's supposed to arrive. When's she due? You know your body better than anyone, so if you truly feel like you are, maybe you should go ahead and give it a go! Or just try to wait another day or two and try again. I with you no matter what you decide, and everything's crossed for you that you get your BFP!
