Femara and ovulation

Tiffany

I had my first pp af and took femara on cd 3-7. I’m currently on day 12 of my cycle and there is no sign of ovulation. I’ve been testing with the clearblue advanced and opk sticks. I’ve been getting low and negative readings since day 9 of my cycle. I’m worried I’m not going to ovulate. Anyone have experience like this? Thanks
