Rating Newest Oldest. Best Answer: It depends on when you ovulate. Sperm can live inside you for 3-5 days. If you have sex before you ovulate then the sperm will hang out in there until you release your egg. Once the sperm reaches the egg and it joins with it then you are pregnant.If you have sex and the egg is already released then it could take a few minutes to a few hours before the sperm joins with the egg.If you are concerned about pregnancy then you can take the morning after pill-it prevents pregnancy from occurring as long as you take it no later than 72 hours after having sex.f you have sex before you ovulate then the sperm will hang out in there until you release your egg.
