No birth control is 100% effective, and there is always the risk of sexually transmitted disease. With that in mind, you have to decide what is 'safe' for you.

You're never safe from getting pregnant. True, at some moments during your period it's a little less likely, but you're never a 100% safe.
It depends on what you mean by "safe intercourse." In using any method of birth control there is always a potential of getting pregnant. Nothing is 100% effective except for not having sex. So, yes, there is a possibility that you may be pregnant.
Yes, it is perfectly safe to do so, unless there are medical reasons not to.
Yes it is.
It is safe at any time, but do you ask in respect of falling pregnant?
Do the intercourse in the safe period. It normally starts from 5 days before the cycle and 10 days after the menstrual cycle.
If you are talking about not getting pregnant w/o using contraception, then the real life answer is - never. Bodies aren't clockwork and may fall out of synch for whatever reasons. One out of five women relying on"safe" days still get pregnant within one year.
Yes, bowling have no effect on your fertility.
Contrary to popular belief, you can get pregnant even while on your period. There are no safe days to have sex without getting pregnant. If you do not wish to get pregnant, always use protection.
Use a condomn and birth control, if worst comes to worse get a morning after pill at you local pharmacy
