Most pregnancies happen after sex within the five days before, and on the day of, ovulation. to conceive , your egg needs to be fertilised within 12 hours to 24 hours of ovulation. it’s also possible to mistake breakthrough bleeding, spotting between your periods, for a regular period.. If you have a regular 28-day cycle and seven-day periods, you can get pregnant five or six days after your period ends. if your cycle or period is shorter, this changes. for example, if your period only lasts for four days, 10 days go by in between when menstruation ends and when you can conceive..
