OPK Question!

Brandi

I am 16 days late for my period. I have just told myself that I missed it, and I need to move on and hope I get it next cycle.

I decided to start taking opk's last week and I have had a blinking smiley face (high) on my tests since last Wednesday. Since I got the first blinking smiley face, I have been testing day and night. Is this normal? When should I expect a solid smiley face (peak)?
