Answer 1

They can’t. The period in which a woman can conceive is just a few days of their cycle. That said the cycle obviously doesn’t match up with the calendar and there are some variations possible which then shifts the fertile period around even more.

Also sperm can also survive up to a few days, which means that the period in which sex can result in conception is a bit longer.
