No ovulation after D and C

Ta
I'm trying not to panic.   In May I had a D and C after being 11 weeks pregnant.  
This month I started using a Clearblue easy read ovulation kit.  I tested every day in the afternoon and I never got a positive for ovulation surge. I've used glow for two years and it's always been spot on. So it freaked me out that on the days I was supposed to be ovulating I never got a positive. 
I'm not sure if I should see my ObGYn or not.  
I'm 30 and still TTC #1 with my husband.  And I don't wait to long long. 
I appreciate any help!!
