clear blue advanced help

Gemma
Hi ladies.. Been using clear blue advanced for ovulation first time this cycle. Had MC last month but had my period before me and my Oh started TTC again. I normally have a 31-33ish cycle and I'm now on CD17 and have had 4 days of flashing smiley face .. Has anyone had this and got peak after? I'm really worried that I'm not going to ovulate 😩 
I'm taking normal OPK to so maybe people could tell me if I'm getting close or not. This is the darkest they have been and I've been tracking since CD8 
Thanks
