is it ever safe to have unprotected sex? i've heard women cannot get pregnant right before their period. is this true?
while there are certain times during a woman's monthly cycle where she may be less likely to get pregnant this is a very unreliable method for preventing pregnancy. first of all a woman would need to know when she's ovulating and most women cannot reliably tell. and even if she can tell there is still a chance she could get pregnant even if she avoids sex for several days following ovulation. i would not recommend this approach if you're trying to prevent pregnancy. it has a high rate of failure. also of course unprotected intercourse always runs the risk of transmitting stds such as herpes gonorrhea chlamydia and even hiv.
