Why havent I ovulated yet?... now 7 weeks post mc :( so discouraged

Hi ladies,

I have been taking advanced clearblue ovulation test every single morning since I stopped bleeding and no sign of ovulation:( .. i dont even have the flashing smiley that would be estrogen surge.. Why is that?! Why havent i ovulated yet? I “should be” cd 16.. before mc my cycles were very regular 28 days

p.s. hcg went back to zero 2 weeks post mc and ultrasound showed everything is out 2 weeks post mc
