Your fertility window explained

Menstrual cycles vary from month to month and differ between people. You can get pregnant during about 6 days each month, called your fertility window.

When ovulation typically happens

Ovulation is thought to happen about 14 days before your next period begins, but it can vary from month to month even if you have regular cycles.

Signs your body is ovulating

Watch for a rise in basal body temperature of typically one half to one degree, higher levels of luteinizing hormone on a home ovulation kit, and cervical mucus appearing clearer and stretchy.

Other ovulation symptoms

You may also experience breast tenderness, bloating, spotting, or slight pain or cramping in your side during ovulation.

Best timing for conception

Your odds of getting pregnant are best when you have sex one to two days before you ovulate. Sperm can survive in your body for up to five days.

Tracking methods to try

Chart your basal body temperature and cervical mucus. Use an over-the-counter ovulation predictor kit, ovulation tracking bracelet, or lab tests to check for hormonal changes before ovulation.

Bed rest after sex doesn't help

It was long believed you should stay in bed for at least 15 minutes after sex to help sperm reach the egg. Recent studies found no evidence to back up this claim.

Weight and exercise matter

Studies show weighing too little or too much may disrupt ovulation and cycle length. Maintain a healthy body mass index between 18.5 and 24.9. Strenuous exercise can mess with your menstrual cycle.

Stress and health conditions affect fertility

Research shows stress may make it harder to get pregnant. Yoga, meditation, and long walks can help. If you have diabetes, asthma, or epilepsy, ensure it's under control.

Partner's health matters too

More than 33 percent of fertility issues involve only the sperm-producing partner, and another 33 percent involve both partners. Both can improve reproductive health by quitting smoking and limiting alcohol.
