really concerned

So according to glow my fertile week ends tomorrow. I'm still having creamy cm and haven't seen any change since my period stopped. I never got watery or egg white cm. I'm afraid maybe I'm not ovulating. I'm trying not to go too far like temping or opk testing because I feel as though that would be too stressful. I have a 26 day cycle and my periods last between 2-4 days.
