Because quinoa is typically consumed in the same way as the cereal grasses (wheat, oats, barley, and rye), we group it together with those foods on our website. However, quinoa is not a cereal grass at all, but rather a member of the same food family that contains spinach, Swiss chard, and beets.
Tracking Your Most Fertile Days. Generally, the highest chance of pregnancy is when sex happens1-2 days before ovulation. If you have a regular 28-day cycle, count back 14 days from when you expect your next period to start. Plan on having sex every other day around that time -- say, days 12 and 14.
Although there is only a 24-hour window during which an egg can be fertilized, sperm can live for three to five days inside a woman's body. So if a woman has unprotected sex three days prior to ovulation, she has a very good chance of getting pregnant. (See How Sex Works for more information.)
