Ung regular menstrual cycle kasi is every 21 days, 28 days or 35 days, pinakacommon jan ung 28 days cycle, kung example every 28 days ka ngkakaroon ng mens nsa 15th day from the start ng mens ung fertile ka or sept 27 ung fertile ka. Ang sperm naman nabubuhay ng 5 days sa loob mo. Kung nakargahan ka ng sperm from sept 23 to 27 malaki ung chance na mabuntis ka, kung 21day cycle ka nsa 7th day from the start of mens, kung 35day cycle ka naman nsa 21st day naman ung fertile day mo, kaya samen pg 22nd day na from the 1st day of mens pwede na mputok sa loob para mas sensual at complete ung satisfaction namin dalawa
