There is no absolutely "safe" time of the month when a woman can have sex without contraception and not risk becoming pregnant. However, there are times in the menstrual cycle when women may be most fertile and are most likely to conceive. The fertile days may last for up to 3-5 days after the end of your period.
How many days before and after period is safe?
You're most fertile at the time of ovulation (when an egg is released from your ovaries), which usually occurs 12 to 14 days before your next period starts. This is the time of the month when you're most likely to get pregnant. It's unlikely that you'll get pregnant just after your period, although it can happen.
How do I know my safe period?
To predict the last fertile day in your current cycle:
- Find the longest cycle in your record.
- Subtract 11 from the total number of days in that cycle.
- Count that number from day 1 (the first day of your period) of your current cycle, and mark that day with an X. ...
- The day marked X is your last fertile day.
