Clomid and day 17 no ovulation

Ciara • We`ve been ttc since July 2014 and had 2 miscarriages in 2015. The first at 12 weeks and the second at 8 weeks.
I'm 8 days post 5 day Clomid round 1 and ovulation tests still showing low fertility on clear blue digital! I thought for sure this month would finally be our month after 2 mc's last year but it doesn't even seem like I'll ovulate now. Doctor said it should happen around day 14. Please help, anybody else had this?
