What is the chance of getting pregnant from one sexual encounter?

That depends on what stage of your menstrual cycle you happen to be in when you have sex.

  • Women are usually only fertile for up to six days per month.
  • Women only have a viable egg for 12-24 hours of those six days.
  • Why am I fertile for six days if the egg is only ready for 12-24 hours?  Sperm can live for several days inside a woman’s body and be ready and waiting to fertilize the egg when it is released. 19,20

Did you know that you are more likely to have sex on your fertile days?

An interesting and possibly dangerous fact, is that women are more interested in sex during the times of the month when they are fertile. 19  That means that even if you are usually very careful to not have unprotected sex, on the days you are fertile, you may be less cautious 56 . Oops! It only takes once.

What are the statistics for pregnancy from one sexual encounter?

We don’t have good statistics for that, but other statistics show that 85% of women who have unprotected sex even only once in a while, will become pregnant within one year.20  The likelihood of getting pregnant from one encounter is obviously much less than 85%, but if you are not ready for parenthood, be sure to have a relationship plan before things get too hot to handle.  Talking with one of our nurses about relationships and sex may be helpful.
