Opks always close but not peak?

Li

Anyone have constant close but not peak opks? I am cd 26 and had one day maybe match the control line but almost every day is close. No peak on clear blue digital just alot of high fertility days. I use clear blue advanced ovulation, easy@home and Premom (quant). Anyone have a better option? I have been doing bbt this month but still so new to that and seems you need months of data to predict
