My fiancé is coming on June 02-17, it was supposedly my ovulation period but I miscalculated. I don't want to have my period during his stay. Can I alter my cycle using pills so I ovulate during his stay?

You can likely alter your periods, but you won't be guaranteed ovulation at a particular time.

There are several birth control pills that can be used to limit periods. Check with your doctor or gynechologist to see which would be best for you to use.
