A menstrual cycle can be as short as 22 days or as long as 36 days. On average, a woman gets her period between 12 days and 14 days after she s ovulated. Women conceive during ovulation and ovulation occurs on day 14 of a 28 days cycle. During the period of bleeding or immediately after period, there is no chance of getting pregnant. Women conceive during fertile period i.e. day 12 to day 18 of the cycle. So relax, there is no chance of getting her pregnant whether you have done penetrative or non-penetrative sex. But remember, slightest penetration of penis inside her can impregnate her but this is only possible in her fertile period (day 12 – day 18), not during bleeding period. Thanks
