The Fertile Window
The fertile window is the three-day window during which the probability of a woman conceiving is highest. Conception is usually defined as the initiation of pregnancy, when an egg is fertilized. This can occur either through in vitro fertilization, or sexual intercourse. In the case of sexual intercourse, sperm remains viable inside a woman's body for up to 5 days (possibly 7 days in some cases). As such, when attempting to conceive, regular sexual intercourse 5 days before as well as on the day of ovulation, can increase the probability of successfully conceiving. This is known as the fertile window.
Furthermore, studies have shown that within this window, the last 3 days are the most fertile days, and sexual intercourse during this period will result in pregnancy in approximately 30% of cases.
Love and Childbearing
The desire to have a child is all about love for your partner, and for the child you will watch grow up.
Deep as this desire is in most couples, life often gets in the way. We stress and worry as a result of work, and spend most of our time dealing with day-to-day distractions and chores. As a result, we do not find the time or do not have the desire to make love as much as we might like to.
Yet, the first thing to know when you are trying to have a baby is that regular sex with your partner is the best preparation of all. When you are trying to have a baby, you should make love regularly - at least 2 to 3 times a week - even when you do not necessarily believe you are fertile or are near your ovulation day.
Tips to Improve Chances of Conception

- Maintain a healthy weight (BMI between 19-24)
- Adopt a healthy lifestyle by quitting smoking and limiting alcohol and caffeine
- Reduce stress and maintain good mental health
- Have regular intercourse before and during ovulation
- Take folic acid and other essential vitamins
Frequently Asked Questions
When is the best time to conceive?
The best time to conceive is typically 2-3 days before ovulation and the day of ovulation itself. Since the egg only survives for about 24 hours after ovulation, while sperm can live in the female reproductive tract for up to 5 days, having intercourse before ovulation ensures sperm are waiting when the egg is released.
How do I know if I'm ovulating?
Common physical signs of ovulation include: cervical mucus becoming clearer and more egg-white in consistency, a slight rise in basal body temperature, mild abdominal pain, increased sex drive, and positive ovulation predictor tests. Using a combination of methods to identify ovulation timing is most accurate.
How long does it typically take to get pregnant?
This varies by individual. About 84% of couples will conceive within one year of having unprotected sex. Age, overall health, lifestyle factors, and potential fertility issues all impact the time to conception. If you've been trying to conceive for over a year (or 6 months if you're over 35) without success, consider consulting a doctor.
How soon after conception can pregnancy be detected?
Most home pregnancy tests can detect pregnancy about 10-14 days after conception (or after a missed period). This is because human chorionic gonadotropin (hCG) needs time to build up to detectable levels in your body. Early detection pregnancy tests may detect pregnancy around 8 days after conception, but results may be less reliable.
What should I do after conception?
Once pregnancy is confirmed, start prenatal care: take prenatal vitamins with folic acid, avoid smoking, alcohol and harmful substances, maintain a balanced diet, exercise moderately, get plenty of rest, reduce stress, and schedule prenatal check-ups. Physical changes and early pregnancy symptoms (like morning sickness and fatigue) are normal, but consult a doctor for severe symptoms.
