12DPO still Negative

I'm 12dpo, been testing with cheapy test strips daily but still negative. AF is scheduled for Wednesday. This whole process is so crazy nerve racking... I feel like tracking all of this information with bbt and opk is putting too much pressure on myself. I've been ttc for 6 months, I really feel for the women out there trying for years!! Planning to schedule a doctor appt to see how everything is working these days...
