Is it safe to fluctuate between going on and going off the pill?
I can think of no medical problems, however you are not going to be protected from prgnancy. If you are sexually active and don't want to be pregnant, stay on some form of birth control.
If you are on the pill but it is for skin care reasons can the pill still be used for safe sex and work?
Is it safe to take the pill and a spermicidal suppository or film as added protection against pregnancy?
I would consider it safe to use another form of birth control along with the pill as long as it didn't contain hormones as the pill does. You don't want to put too many different hormones in your body. If you can buy it at a store without a prescription from a doctor, it's probably safe to take with the pill. But read the package just to be safe. It will say on the package…
