The solution? Have sex about three times a week (having it too often may reduce sperm count). Sperm can live up to three days in a woman's body, so you'll increase your chances of getting pregnant, even if you have sex three days before you ovulate.
By charting your temperature for several months, you'll be able to calculate when you ovulate a little more easily, and therefore increase your chances of getting pregnant.
Why is this? Simply put--gravity. Lying on your back with your hips tilted up will encourage the flow of semen to your uterus.
While no studies have directly linked sunlight and conception, it can't hurt to get a little extra. Just remember to keep unprotected exposure down to only 5-10 minutes, so as not to damage your skin.
In addition, the amount of vitamin D found in foods is often negligible, so many experts recommend a dietary supplement to ensure your vitamin D needs are met.
Just remember, this isn't a sure-fire way to increase sperm count. If you and your partner are having trouble conceiving, getting him tested for low sperm count is something to consider.
In addition, start loading up on folic acid by taking a daily prenatal vitamin. The Food and Drug Administration recommends all women trying to get pregnant fuel up on this B vitamin to help protect against serious birth defects that affect a fetus' brain and spinal column.
So be sure to look for "BPA-free" on plastic products, especially those in contact with food.
