Q: Can I go swimming the day after we make love? Can the water enter my uterus and prevent me from getting pregnant?
A: Swimming or taking a bath are not contraindicated while you are trying to get pregnant. After you make love, sperm enter your uterus within minutes. The rest die quickly in your vagina. When you take a bath or go swimming, the water does not enter your uterus, does not interfere with the sperm in the uterus, and does not affect the fertilization process.
