Is it possible for women to become pregnant if she make contacts on her 5th day period?

Yes.

It's possible on any day. The probabilities just go down during her period, but pregnant is pregnant, even if she only had a low probability that day.

Agreed, while a lesser chance there are chances of becoming pregnant if you have sex during your period.

NO

NO

Surprisingly to many, it is possible. If crizza happens to ovulate earlier than the norm, which some women do, she could indeed become pregnant from sex on the 5th day of her period.

Her body may be preparing for ovulation at that time, in which case some sperm may survive long enough to fertilise the egg when it is released days later.

It is not the norm, but it can happen.
