AF was supposed to arrive today but still no show. I usually start around 6am. I am estimating that I am 14dpo. I took a cheap walmart test this evening because I didn't wanna wait Til in the morning. It was a BFN...  How often should I test If AF doesn't show up until I do get a BFP? Daily, every other day, or every couple days? I don't want to waste test but I am sooo impatient!
