    Why only after 6 PM? Can I have safe unprotected sex in the morning?

    Hey there,

    The 6 PM rule is there to give any cervical fluid enough time to descend through the vagina throughout the day. Though unlikely, it's possible that sperm from unprotected sex in the morning could survive long enough to meet fertile cervical fluid in the afternoon. 

    However, if you verify before having sex that there is no cervical fluid at the os (cervical opening), and that your cervix is in its most infertile position (low, firm, and closed for most women), your increased risk of pregnancy is probably very small. I say 'probably' because no studies have been done on the matter - so it's up to you whether you want to take on a slightly increased risk of pregnancy.
