calendar method

Ginagamit lang ang calendar method if regular ang menstration mo. Halimbawa, ang mens mo ay nagsisimula every may 14, at nag tatagal hanggang 4-5 araw, start counting backwards for 3 days (that is may 11)before mens, that’s safe if gusto nyo mag sex... kapag naman after mens you can also count 3 days after mens(that is may 20,after 3-5 days of having mens) that is still safe if magssex kayo. So paano ang hindi safe magsex? If nakalipas na ang 3-4 days tsaka palang kayo magssex yun ang not safe.. meaning pagkalipas ng 3-4 na arw ng huling mens mo, by that time nagstart na ulit ang fertility cycle mo, at maari kang mabuntis anytime. Sana na gets mo ang explanation ko! 👌🏻 hehehe P.S. yung 3days before and after yan ung days na safe magsex.. (Within that 3 days)Not counted as safe if you’ll be having sex after 3 days had pass
