Usually your period comes later. But sometimes you have to get meds to start AF. Did you have b/w done to tell you that you didn't ovulate? FYI...I ovulate late on Clomid...cd21 instead of the usual 14. My dr. told me thatI didn't ovulate when really I did.
I charted my temps and cm and went back in a week later for more b/w and they said I really did ovulate...just later than they've seen before. Good luck to you!

to us all.
