There is never a "safe" day to have unprotected sex. Any time you have unprotected sex, you risk pregnancy. If you're not ready for a baby, please use a condom.

As the previous poster stated...there is no safe period when a woman cannot get pregnant. Remember the sperm can live inside the vagina for more than 1 day.

There is never a certain time in a woman's cycle when pregnancy is not a risk, ok yes there are time when it is less likely but if you did choose to have unproted sex without wanting a child then you are just playing with fire
