Doctor ordered clomid (clomiphene) days 5 to 9, clearblue digital opks starting day 12. is this early enough to catch any possible surge? i am on day 13 now.

Maybe: You generally ovulate 5-10 days from the last Clomid (clomiphene) pill. If you take the pill days 5-9 than you will ovulate somewhere between days 14-19 days from the start of your period. So starting the odk around day 12 should be perfect. Once the odk shows a surge, ovulation generally occurs 26-40 hours later. Hope this helps. Good luck.
