What are the days after periods should I stay out of sex to avoid pregnancy?

Hello,

Welcome to icliniq.com.

Your question actually pertains to a natural birth control method called the rhythm method calendar method (you can search for it online). Let me tell you, the safe days are the ones you can actually have sex to avoid pregnancy, but this method is unreliable, and there are failure rates too. Consider the first day of your cycle (menstrual cycle (the day from which you began to bleed.

You keep track of your cycles and determine your shortest and longest cycle, but before that, know that your cycles must be regular. Subtract 20 from your shortest and ten from your longest cycles, and you get your safe days. For example, if the shortest cycle is of 26 days and the longest one is of 30 days, then 26-20= 6 and 30-10= 20. Hence, days 6 to 20 are unsafe for you. Rest all will be safe to have sex to avoid pregnancy. There are many other calculations for the calendar which you can search, but my recommendation will be five days after the last day of your first cycle; that is when the bleeding stops will be the safest (though not 100 percent).
