Advice please!

So hubby is traveling 16th-20th.

According to app, my ovulation day is the 16th. fertile window 11th-16th. I’m about to start Clomid in 2 days for cd5-9. Will that make my ovulation day change to a few days later? I normally O cd11-13. I hope not because then hubby will be gone for the whole fertile window. I don’t want my Clomid cycle to go to waste.
