Yes, it's true that pregnancy can only happen during your fertile window, which is the few days around ovulation (about 5 days before and the day of ovulation), because sperm can live inside the body for several days, waiting for the egg to be released, while the egg is only viable for 12-24 hours after ovulation, making conception highly unlikely outside this brief period.
“Even if your cycles are regular, the timing of ovulation can fluctuate slightly from month to month,” points out Dr. Twogood. “So you could get pregnant outside your expected fertile window because ovulation may take place earlier or later than you estimated.”
Whether you want to conceive or want to avoid pregnancy, knowledge of your unique cycle can increase the chances of avoiding or conceiving. Keep in mind that even during the most fertile window, pregnancy is not guaranteed—and that's completely normal.
Having sex regularly from 3 to 4 days before ovulation until one day after ovulation improves the odds of getting pregnant. Pregnancy is most likely to happen in the days surrounding ovulation. So if you want to get pregnant, it's important to know when you're ovulating.
You are at your most fertile just before you ovulate, on the day of ovulation, and up to a day after you ovulate. This week or so around when the egg is released is often referred to as the 'fertile window'.
You are least likely to get pregnant right before and during your period, and in the days after ovulation, as fertility is lowest when you are not ovulating or your egg has already passed. However, due to cycle variability, no time is 100% "safe," and pregnancy is always possible, so barrier methods (like condoms) are crucial if you want to avoid pregnancy, says Flo app and Kids Health.
Four common signs of ovulation are changes in cervical mucus (becoming clear, stretchy, like egg whites), mild lower abdominal pain or cramping (mittelschmerz), a slight increase in basal body temperature, and an increased libido or sex drive, though not everyone experiences all these signs. Other indicators can include breast tenderness, bloating, light spotting, or mood changes, as hormonal shifts prepare the body for a potential pregnancy.
7 Signs It May Be Easy For You To Get Pregnant
Knowing when you ovulate and having sex regularly from 3 to 4 days before ovulation until one day after ovulation improves the odds of getting pregnant.
The 7 key signs of ovulation include changes in cervical mucus (becomes clear, stretchy like egg whites), a slight rise in basal body temperature, mild one-sided pelvic pain (mittelschmerz), increased libido, breast tenderness, bloating, and sometimes light spotting, all driven by hormonal shifts that signal your most fertile window.
45% of young couples (under 35) will conceive after three cycles of unprotected sex. 65% of couples conceive after six cycles of unprotected sex. 85% of couples will conceive within the first year of regular unprotected sex.
To protect your fertility, make these healthy lifestyle choices:
These six days are referred to as the “fertile window” of a woman's cycle and reflect the lifespan of sperm (5 days) and the lifespan of the ovum (24 hours). The key to conception is having sex during that small window of time, when the ripened egg is released from one of the ovaries and moves into the fallopian tube.
The "3 over 6 rule" in fertility awareness methods (FAMs) confirms ovulation by identifying a sustained rise in your Basal Body Temperature (BBT): it requires three consecutive days of temperatures higher than the six days before them, with the third high temperature being at least 0.2°C (0.4°F) above the preceding six days' highest point, marking the end of the fertile window for avoiding pregnancy and confirming ovulation has occurred. This rule, used with other signs like cervical mucus, helps pinpoint the infertile phase after ovulation, but it's not an exact science and requires careful daily tracking.
At least 85% of women, who continue to have sex without birth control, even just once in a while, will be pregnant within one year. A woman will only get pregnant if she has sex without birth control on the day she ovulates (releases an egg).
Sperm typically can stay alive for about 3 to 5 days within the cervix, uterus and fallopian tubes. It's possible for an egg to be fertilized at any point during that time. The likelihood of pregnancy is highest when live sperm are in the fallopian tubes when an egg is released from one of the ovaries.
High fertility in women is indicated by regular menstrual cycles, healthy cervical mucus, optimal hormone levels (AMH, FSH), a healthy BMI, and minimal PMS symptoms.
Ovulation detection kits are the most accurate way to track ovulation each cycle. Other methods like BBT, cycle, discharge and saliva tracking are not as accurate but can still be useful.
Is there anything you can do to boost your chances of sperm fertilizing an egg? Ideally, you need to have sex no more than five days before ovulation in order for fertilization to occur. You can boost your chances of fertilization by tracking your cycle and having sex as close to ovulation as possible.
Normally, semen is a thick liquid and is white in color. However, several factors can alter the color and consistency of semen. Watery sperm can be a sign of low sperm count, indicating that fertility may be affected. Watery sperm can also be a temporary condition that does not seriously impact health.
As ovulation nears, your discharge will become wet, stretchy and slippery. The most common analogy for super fertile cervical mucus is looking and feeling like raw egg whites. If you see that texture, you'll know you're at your most fertile time.
A woman in her early to mid-20s has a 25–30% chance of getting pregnant every month. Fertility generally starts to slowly decline when a woman is in her early 30s, and after the age of 35 the decline speeds up. By age 40, the chance of getting pregnant in any monthly cycle is around 5%.
For men, some of these signs include a healthy sperm count, high-quality sperm that can swim quickly and easily, and a good balance of hormones. For women, good fertility indicators include regular ovulation, the presence of cervical mucus, and the regularity of menstrual cycles.

Ovulation usually happens once each month, about two weeks before your next period. Ovulation can last from 16 to 32 hours. Ovulation does not happen if you are: on the contraceptive pill.
