Doubting myself!

Hello everyone me & my husband have been TTC since last month, this month I have had 6 blinking smiley faces using the clear blue advanced digital no solid face yet. Is it normal to have 6 blinking smiley faces with no peak yet? Also my period cycle has been different lately it used to be at least 28 days now it is 19-21 days depending on the month. My next period is coming on March 6th according to the app but it usually comes a few days or a week before since it is changing. Do y’all think I will reach peak before my period comes or is it too late?
