Overview
When couples start trying to get pregnant, they often wonder if they are doing everything right and how they can get pregnant faster. While it may not be rocket science, there is still a fair amount of science behind the process of pregnancy. The most important factor in conceiving fast is the right time and frequency to have unprotected intercourse. So if you are in the same boat, find expertly given, research-backed tips to help you conceive faster in this article. We have also mentioned what myths you should not fall for when it comes to the best time to conceive.
Understanding the Menstrual Cycle
The key factor in pointing out the best time to conceive is knowing when you ovulate. For this, you must first understand your menstrual cycle.
- Day 1 of your menstrual cycle : this is the day your period starts. The length of your menstrual cycle is from one period to the next. So, if your next period comes 28 days after your last period started, your menstrual cycle is 28 days long.
- Ovulation : You usually ovulate in the middle of your menstrual cycle. If your cycle is 28 days long, you are likely to ovulate on the 14th day.
- Luteal Phase : The second half remains roughly the same length, approximately 14 days. After ovulation, your body produces progesterone to prepare the uterus for pregnancy. If pregnancy doesn’t happen, progesterone drops, and your next period begins.
What Is the Fertile Window?
Your fertile window is basically the period when ovulation occurs. This is the time when the egg is available for fertilisation/ the sperm and egg need to meet in the reproductive tract during this time to initiate fertilisation.
Once the egg is released from an ovary, it can survive 12-24 hours in the fallopian tubes. Moreover, the sperm can survive in the woman’s reproductive tract for 3-5 days. That means your most fertile days are the 3-5 days before ovulation and the day of ovulation itself. Having intercourse regularly in the five days leading up to ovulation gives the best chance of sperm being ready when the egg is released.
How to Know When You’re Ovulating
Now that we know that pregnancy occurs when you have intercourse during ovulation, it is important to know when you are ovulating. Here are a few things to keep in mind when tracking your ovulation cycle.
- The calendar method doesn't always work : most women assume that ovulation will occur on the 14th day of their cycle. This is not always true. The day of ovulation will vary for women. Some women have a menstrual cycle of 24 days; others have a cycle of more than 30 days. Moreover, cycles can vary from month to month, and stress, illness, travel, or hormonal changes can shift ovulation. The calendar can provide a rough estimate, but it’s not always reliable on its own.
- Check for signs : ovulation is mostly accompanied by the following symptoms:
- Stretchy, thin cervical discharge
- Rise in basal body temperature. You can use a basal body thermometer to track your temperature throughout the month and look for patterns on the day it shows a rise.
- Breast tenderness
- Increased desire to have sex.
- Mild pelvic or abdominal pain is called mittelschmerz. There may be a slight twinge or ache on one side of the lower abdomen.
- Get ovulation kits : Ovulation predictor kits test your urine for the LH surge. This is the hormone that rises 24–36 hours before ovulation. This may be the most accurate method for predicting your ovulation days.
How Often to Have Intercourse During the Fertile Window
- Alternate days are fine : According to the American Society for Reproductive Medicine (ASRM), couples who have sex every other day during the fertile window have the highest conception rates.
- No need for daily sex : Sperm can remain viable in the reproductive system for 3-5 days after a sexual encounter. Therefore, there is no need to have sex daily
- Do not go for multiple times on the same day : Some people even go to the extent of having sex multiple times during the same day. They think this increases their chances of conception. On the contrary, it may lower sperm quality.
- Avoid long gaps : while sperm remain viable for 3-5 days in the reproductive tract of women, do not go for more than 4-5 days without having sex during the fertile day.
Myths About the “Right Time” to Conceive
| Myth | What Science Says |
|---|---|
| You can get pregnant any day of your cycle. | Only during the fertile window when ovulation occurs. |
| Day 14 is the same for everyone. | Ovulation timing varies with cycle length. |
| Resting after sex increases chances. | There’s no strong evidence for this; sperm reach the cervix within minutes. |
| Certain positions guarantee pregnancy. | Timing matters more than position. |
| You can’t conceive during irregular periods. | You can. Ovulation still occurs, just less predictably. |
Factors That Can Shift or Affect Ovulation
Women's hormones are easily affected by several factors, so if you are thinking of getting pregnant, keep these factors in mind to ensure the best chances of conception and a healthy pregnancy:
- Sudden weight changes : Being underweight or overweight affects hormones.
- Health issues : Thyroid issues, Polycystic Ovary Syndrome (PCOS), insulin resistance, etc., cause irregular or absent ovulation.
- Excessive exercise : Overtraining can disturb reproductive hormones.
- Age : After 35, ovulation may become less regular as ovarian reserve declines.
- Bad lifestyle choices : overeating, sedentary lifestyle, and the use of alcohol, smoking, or other substance abuse can all negatively impact your overall health, impacting ovulation and the quality of eggs.
- Stress : High stress can delay or suppress ovulation.
Timing, Hormones, and Fertility Signs
| Cycle Day (in 28-day cycle) | Hormone Activity | Typical Signs | Fertility Level |
|---|---|---|---|
| 1–5 | Menstruation | Bleeding, low hormone levels | Not fertile |
| 6–9 | Follicular phase | Cervical mucus starts increasing | Low–medium fertility |
| 10–13 | Oestrogen rise | Clear, stretchy mucus, libido increase | High fertility |
| 14 | LH surge → Ovulation | Mild pain, temperature dip or spike | Peak fertility |
| 15–18 | Egg gone, progesterone rises | Mucus dries up | Fertility drops |
| 19–28 | Luteal phase | Stable BBT, PMS possible | Not fertile |
