Ovulation question!!! PLEASE HELP!!!

Michelle • Married 10.24.14 ttc baby #1 diagnosed with pcos in 2015
My husband and I are trying to conceive I was told I have pcos.. I was heart broken but doctor said she was very hopeful. I am on metformin 2000mg a day and I took clomid 100mg days 3-7. I go in tomorrow to get a hcg shot but according to a clomid <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation calculator</a> I can test today to see if I am ovulating which I did and it came up negative so does that mean the clomid didn't work? Or will it say negative until I get the shot tomorrow?? Please anyone help!!! I just want to be a mom!!!
