Are there "safe days" during the month which a woman can't get pregnant?


Many women believe that there are certain days during a woman's menstrual cycle when she will not be able to get pregnant. Therefore, some women may feel that it is okay to have unprotected intercourse during this time for there is no risk of pregnancy. It is true that there are certain days during the menstrual cycle that a woman is particularly fertile and has a risk as high as 30% of getting pregnant. Consequently, there are other days in the cycle that the risk of pregnancy is much lower. However, there are many factors that prevent these certain days from being completely "safe". For example, a woman's menstrual cycle my be irregular, therefore making it difficult to predict the "safe days". Furthermore, sperm can survive in a woman's body for three to five days, as long as cervical fluid is present. It is possible, although unlikely, that a woman may become pregnant while menstruating. So, there really aren't any "guaranteed safe days" where the is no risk of pregnancy.

Just as important, unprotected sex always carries the risk of speading certain STI's. There are no "safe days" for STI contraction.
