Not ovulating

Tonya
I've been TTC for only 3 months now but have been taking a fertility test every other day this month. They have all been negative and I don't think I'm ovulating. The doctor said to call back after 6 months if I was having trouble but I am anxious and don't want to waste 3 more months of I'm not ovulating! I don't know if I should call now or wait....
