Femara-did you ovulate late?

Courtney
This is my 4th month of taking meds to ovulate...first two months 50mg of clomid, 3rd month 100mg clomid...and still never ovulated in those cycles apparently 😞. I started 5mg of Femara this month, I'm on cd13 & my opk doesn't seem to be getting any darker. I'm bummed that this round may not make me ovulate either! 
Been ttc for about a year & a half now for baby #2.  And I have PCOS as well.
