Multiple smiley faces in 7 days

I tested constantly. On a sunday I got a solid smiley face 2 days later got a blank circle in the morning at lunch had a blinking smiley face tested again that afternoon got a blinking smiley face. Wednesday got blinking smiley same on thursday. Friday I got another solid smiley face. Two days later on sunday when the smiley cleared took it again and got another solid smiley face. This was two weeks ago. Last week got several blinking smiley faces and just took one a few min ago and got a blinking smiley face. Is this normal? My cycle is scheduled to start in 10 days.

most of the things i have read does not say anything like this. 
please help. We have been trying to concieve for months. 
is this normal to have that many solid and blinking smiley faces?
