    After Sex How Many Days to Get Pregnant: Your Timeline to Conception

    Updated on 23 May 2023

    As soon as a couple decides to grow their family and begin their conception journey, their mind is overwhelmed with numerous questions. After sex how many days to get pregnant, what’s the science behind conception and what are the early symptoms of pregnancy are some questions that may come to the mind.

    In this article, we will understand how many days does it take to get pregnant, a day-by-day conception timeline, how soon can you take a pregnancy test to help you in your journey to see those two lines on the pregnancy test.

    After Sex How Many Days to Get Pregnant?

    Conception can occur within three minutes of sex or up to five days later, but it may take up to a year or more for couples under 35 to conceive. The fertile window is crucial for conception, and an egg can only be fertilized within 12-24 hours after ovulation.

    However, because healthy sperm can live for several days inside the reproductive tract, it's possible to conceive having sex up to five days before ovulation and even within 30 minutes after ejaculation.

    Conception Timeline

    So, now, let us find out how many days does it take to conceive right after sex.

    15 to 45 minutes After Sex: The Sperm Travels

    The most important thing to get pregnant is for the sperm to travel to the egg, which is in the fallopian tube. For this, it’s essential for a couple to have sex for about 5 days until ovulation because it is during ovulation that the female body releases an egg.

    Millions of sperm released during sex travel to the egg but only about 200 sperm actually reach the egg. The journey of sperm reaching the egg is usually completed within 15-45 minutes after sex.

    45 minutes to 5 days After Sex: Fertilization

    Once the sperm reaches the fallopian tube, it waits for the egg for the next 5 days. When the egg is released during ovulation and the sperm enters the egg wall, this process is called fertilisation.

    When the sperm meets the egg, it is fertilised and this fertilised egg eventually becomes a zygote, which becomes an embryo. This process of fertilisation can take between 45 minutes to 5 days after sex.

    6 days to 10 days After Sex: Implantation

    After the sperm has fertilised the egg, the egg begins to divide rapidly and becomes a cluster of cells. This cluster of cells eventually becomes the embryo. As this cluster grows, it begins to travel from the fallopian tubes to the uterus, where implantation occurs.

    When a fertilised egg attaches itself to the uterus lining, it is called implantation. This process takes about 6-10 days after sex.

    2 weeks to 4 weeks After Sex: Early Pregnancy Symptoms

    As soon as the embryo implants itself in the uterus, the female body begins to produce hormones which result in early pregnancy symptoms. Some common early pregnancy symptoms include implantation bleeding, breast tenderness, morning sickness, frequent urination, mood swings and missed period.

    When to Take Pregnancy Test After Sex?

    Now that you know after sex how many days to get pregnant it can take, it’s also important to know when to check for pregnancy. If you’re experiencing any of these symptoms, then you must take a pregnancy test to find out whether you’re pregnant or not. But it’s important to know the right time to take a pregnancy test.

    You should wait at least ten days from unprotected sex to take a home pregnancy test. This is because implantation occurs after 10 days of having intercourse. Waiting until after you miss your period can provide more accurate results as taking a test too early can lead to false negatives.

    Essential Things to Keep in Mind While Getting Pregnant

    Now that you know how many days does it take to get pregnant, it’s also important to know certain factors that can affect your chances of conception.

    1. Taking account of your eggs

    A woman is born with 1-2 million eggs. By reaching puberty, she has around 300-5 lakh eggs left, and the number continues to decline gradually. By the age of 37, a woman is down to roughly 25 thousand eggs and only a thousand eggs by the age of 51, when most women reach menopause.

    2. Age factor

    A woman’s fertility begins to decline with age and so do her chances of pregnancy. Women in their twenties have a higher chance of getting pregnant than women in their thirties and forties. The chances of getting pregnant decrease as a woman ages due to a decline in the number and quality of eggs.

    3. Body weight

    Body weight above healthy BMI (Body Mass Index) can decrease your odds of becoming pregnant. So, it is necessary to closely check your food intake, diet, and exercise to maintain a healthy BMI. A healthy BMI can help clear some of the common roadblocks to pregnancy.

    4. Tracking ovulation

    Instead of just plain guessing, it is advisable to start tracking ovulation to find your most fertile window and increase your chances of conception. Recording your basal body temperature and tracking your menstrual cycle can also help identify the best days for getting pregnant.

    5. Egg freezing

    Nowadays, women commonly delay having kids until their late 20s, 30s, or early 40s. Instead of letting the biological clock tick by, women can opt for egg freezing or embryo freezing. This can help preserve a woman’s eggs and help her get pregnant when she’s ready.

    Key Takeaways

    In answer to the question after sex how many days to get pregnant, the timeline to conception after sex is not an exact science. It can take place as soon as three minutes after sex or up to five days. Couples under 35 years old may take an average of a year or more to conceive. However, mistiming sexual intercourse is a common cause of delay in getting pregnant. By understanding the basics of the process, couples can take steps to increase their chances of getting pregnant.
