When sperm travels up through the vagina, into the uterus, and fertilizes an egg found in the fallopian tube, conception occurs.
Conception happens during the part of a woman’s menstrual cycle called ovulation, which is around the end of week two, this can be different based on a woman’s cycle. Conception comes down to timing, the health of a woman’s reproductive tract, and the quality of a man’s sperm.
Most doctors usually recommend having unprotected sex starting about three to six days before you ovulate, as well as the day you ovulate if you wish to become pregnant. This increases the chances that sperm will be present in the fallopian tube to fertilize the egg once it’s released.
