Birth Control Myths (cont.)

A woman can get pregnant any time ovulation occurs, even if it is your first time having sex.

  1. I won't get pregnant if I take a shower or bath right after sex, or if I urinate right after sex.

Washing or urinating after sex will not stop the sperm that have already entered the uterus through the cervix.

  1. The pill is always effective immediately after you begin taking it.

In some women, one complete menstrual cycle is needed for the hormones in the pill (oral contraceptive) to work with the woman's natural hormones to prevent ovulation. Some doctors recommend using a back-up method of birth control the first month of taking the pill.
