Maybe I'm going crazy..

This was supposed to be my most fertile week, but with this whole yeast infection ordeal, I don't wanna have any kind of extra intrusion on my lady bits.. I've been TTC since March, and every test has always been BFN - now I'm wondering if this yeast infection is a possible indicator of early pregnancy? I've not experienced any other symptoms, but I want to know what yall think and if you've had any similar experiences..
