According to Baby Center, the easiest way to get pregnant is by determining when ovulation occurs and then having sexual intercourse around those days, which is when a woman is most fertile. A woman usually ovulates 14 days before the start of her next period, according to WebMD.
Sperm live three to five days, according to the Mayo Clinic. Once the egg is released, it spends up to 24 hours in the fallopian tube waiting for sperm to fertilize it, according to WebMD. So, the best time for intercourse is up to five days before and one day after ovulation occurs.
