How to Calculate Days to get Pregnant

By eHow Contributor

You can determine the best days to get pregnant in a woman's cycle to increase your odds of conception. Since women are potentially fertile only a few days out of each month, pinpointing those days for TTC (trying to conceive) greatly increases your likelihood of getting pregnant. The woman and her partner should learn to be in tune with her body and its cycles, discovering the signs that indicate fertile days, in order to increase their chances of getting pregnant right away.

Track your cycle, noting the day it begins (first day of menstruation) and ends every month. The last day of the cycle is the day before the next period begins. Knowledge of average cycle length will help you discover the best days to get pregnant.

Note cervical mucous, or vaginal discharge, during the month. Toward the middle of the cycle, quantity increases and it becomes clear, stretchy/runny, and mimics the look of egg white. This fertile mucous is one of the best indicators of impending ovulation.

Count backwards from the end of the cycle to 10 and 14 days before your next cycle started. This is the time of ovulation, and that four-day window, combined with positive mucous, represents the very best days to get pregnant in a woman's cycle.

For a 28-day cycle, the best days to get pregnant are days 14-18. For women with 30-day cycles, they will be most likely to conceive on days 16-20.

Recognize mid-cycle cramping that may indicate ovulation. This is yet another sign of female fertility, though it is not experienced by all women, and it can help you find the best time to have intercourse in the hopes of conceiving. For some, tender breasts are another possible sign.

Combine the knowledge of your cycle length, ovulation dates and cervical mucous as well as secondary signs (cramping, breast tenderness) to find days to get pregnant -- and take advantage.

If low sperm count is suspected or confirmed, time the "trying" to every other day during the fertile window.
