Am I crazy?

Anna • 29, TTC#1
Or is this a very faint BFP?  Obviously I'll retest as days go by...but that faint line is making me trip balls. I also have drank about 100oz of water today so could that impact line appearance? 
 
​I'm not sure what DPO I am. I really only started tracking this month. I'm not expert in pregnancy tests so I'm just not sure what is bull and what isn't. Thanks for any clarification, ladies.
