Ewcm 5-6dpo

Hello all! I’m just confused. I took letrozole cd3-7 of cycle on cd 10 had an ultrasound confirming I had multiple follicles one of which had already ovulated and the others about to. Cd11 had peak opk on clear blue advanced. Had heavy ewcm for cd10-12. Now on cd15 I am having ewcm again. So my question is am I off on my guess for ovulation. I haven’t started temping yet but will if this cycle doesn’t work. Waiting until at least cd24 to test. If I can it will be cd 28. Any thoughts?
