[/INST] Hi, How are you doing ? If you are having periods every 29 days or so, your ovulation is occurring on Day15 of the periods (first day of periods being the first day of bleeding)Life of egg is 24 hrs & that of sperm is 72 hrs. So having sex around 12-18th day of periods, any number of times, will have high chances of pregnancy. Hope I have clarified your queries, do write back if anymore queries the best Chat Doctor.  </s>
