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.
While ovulation itself only lasts for 12 to 24 hours, you're most likely to get pregnant in the days before and after ovulation, a window of around six days.
As you get close to ovulation, your cervical mucus will become copious, clear and slippery—like egg whites. It stretches between your fingers. Once your discharge becomes scant and sticky again, ovulation is over.
Pregnancy After Ovulation
Getting pregnant after ovulation is possible, but is limited to the 12-24 hours after your egg has been released. Cervical mucus helps sperm live up to 5 days in a woman's body, and it takes around 6 hours for active sperm to reach the fallopian tubes.
Early signs and symptoms include implantation bleeding or cramps, which can occur 5–6 days after the sperm fertilizes the egg. Other early symptoms include breast tenderness and mood changes.
If she has sex five days before she ovulates, her probability of pregnancy is about 10 percent. If she has sex on the day of ovulation, or the two days before, the chance of getting pregnant is around 30 percent.
Once the sperm enters the reproductive system, it can take about 30-45 minutes to reach the egg. For this, it is important to have a healthy sperm which has the right kind of motility to reach the egg and fertilize it. Once inside the body of a woman, a healthy sperm can live up to 2-5 days.
In other words, it means an egg is being released from your ovaries on a regular basis. But, ovulation alone does not guarantee that you can get pregnant. Sometimes there can be an issue with egg quality, how the egg is fertilized, its ability to be transported to the uterus, or how it becomes implanted in the uterus.
Fertility is most likely if the semen discharged in a single ejaculation (ejaculate) contains at least 15 million sperm per milliliter. Too little sperm in an ejaculation might make it more difficult to get pregnant because there are fewer candidates available to fertilize the egg. Movement.
Most couples will get pregnant within a year if they have regular sex and don't use contraception. But women become less fertile as they get older.
The Odds of Getting Pregnant
For most couples trying to conceive, the odds that a woman will become pregnant are 15% to 25% in any particular month. But there are some things that can affect your chance of getting pregnant: Age.
You ovulate about 12 to 14 days before the start of a new menstrual cycle. Your fertile window is the five days leading up to ovulation, plus the day of ovulation and the day after ovulation — so about seven days in total.
The sperm enters the egg in the fallopian tube. It can happen even 3-5 days after ejaculation. There is no way for either of the partners to know if the sperm entered the egg. The only way to know for sure if the sperm did enter the egg is after a positive pregnancy test.
Aiming for the man to ejaculate as deeply as possible into the woman's vagina. This means that the smallest amount of semen escapes and is retained as close to the cervix (the neck of the uterus) as possible. The woman can try lying on her back with her lower back elevated on a small pillow for around 20-30 minutes.
An egg should be released within one to three days of the positive ovulation test. Once an egg is released, it is viable, or fertile, for around 24 hours. Sperm remains viable for even longer, and can live inside a woman's body for up to five days.
Peak male fertility is around 25-29 years old. Sperm quality begins to decline at 30. At 45, men begin to experience a significant decrease in semen volume. Older men can also take longer to conceive a child.
Risk factors for a high-risk pregnancy can include: Existing health conditions, such as high blood pressure, diabetes, or being HIV-positive. Overweight and obesity. Obesity increases the risk for high blood pressure, preeclampsia, gestational diabetes, stillbirth, neural tube defects, and cesarean delivery.
“Even if you have [unprotected] sex on the right day of the month, there's still only a 20 percent chance of conceiving [from that session].” Since sperm can live in your uterus for a few days, she recommends “getting some in there in advance” of ovulating.
Sex after ovulation
Remember as well that the day after ovulation is one of the best days for the chance of conception, so there's no need to stop having sex, and in fact every reason to carry on. Research has also found that regular sex is beneficial for the health of sperm.
Risk factors
age – fertility declines with age. weight – being overweight or obese (having a BMI of 30 or over) reduces fertility; in women, being overweight or severely underweight can affect ovulation. sexually transmitted infections (STIs) – several STIs, including chlamydia, can affect fertility.
Of all couples trying to conceive: 30 percent get pregnant within the first cycle (about one month). 60 percent get pregnant within three cycles (about three months). 80 percent get pregnant within six cycles (about six months).
Conception is most likely to occur in the first month of trying (about a 30% conception rate). The chance then falls steadily to about 5% by the end of the first year. Cumulative conception rates are around 75% after six months, 90% after a year, and 95% at two years.
The results: After one month of trying, 38% were pregnant. After three months of trying, 68% were pregnant. After six months of trying, 81% were pregnant.
