Clearblue advanced Ovulation Kit..HELP!


Okay I've been using this for a couple of days now and I've gotten Low. According to my <a href="">period app</a> I'm suppose to ovulate shouldn't I have already seen a smiley face? I'm soooooo sooo new to this ha!! I have no idea what I'm doing. Should I be testing more then once a day? I've been following the instructions and testing first thing in the morning but only once a day.
