Ovulation Test

Question; glow has been right so far the last 4 months of when I'm gonna get my period, when I'm ovulating etc... Yet I'm still not pregnant and I just had my tubes and hormones check and my husband also got checked. Fertility doctor says my tests all came back phenomenal. That I should be pregnant in no time... Here's the problem. I took the ovulation test (clear blue) as I regularly do, and even though GLOW says it's my highest fertility day today. My test came out saying I'm not ovulating... Has this happened to anyone else????? :/ I also have never been able to know when I actually am without testing because I don't discharge. I have two kids alreDy but even so, have never had discharge in my life! I'm basically always dry. So no, I don't ever see that clear egg stuff everyone talks about and im in my mid 30's someone help... I'm feeling depressed.....
