These are the days you are most likely to get pregnant. A few days before ovulation, you may notice your vaginal mucus becomes clear, slick and slippery, and feels a bit like egg white. This is a sign that ovulation is about to happen. You can use a predictor kit from a supermarket or pharmacy, to test your urine for signs of ovulation. If you start testing your urine a few days before the day you next expect to ovulate, a positive result means you are going to ovulate within the next 24 to 36 hours one to two days.
Ovulation is when a mature egg is released from the ovary. The egg then moves down the fallopian tube where it can be fertilised. If sperm are in the fallopian tube when the egg is released, there is a good chance that the egg will be fertilised, creating an embryo, which can grow into a baby. Pregnancy is technically only possible if you have sex during the five days before ovulation or on the day of ovulation. But the most fertile days are the three days leading up to and including ovulation.
Having sex during this time gives you the best chance of getting pregnant. By hours after ovulation, a woman is no longer able to get pregnant during that menstrual cycle because the egg is no longer in the fallopian tube. Knowing when you ovulate can help you plan for sex at the right time and improve your chance of getting pregnant. You can keep track of your menstrual cycles on a chart, in a diary, or on a free period-tracker app on your smartphone.
To work out the length of your menstrual cycle, record the first day you start bleeding first day of your period. This is day 1. The last day of your cycle is the day before your next period begins. A menstrual cycle starts on the day when a period starts day 1 and ends the day before the next period. They can vary between women and from one cycle to the next. Periods are not always regular. If you add the number of days in three cycles and divide the total number by three, it gives you your average cycle length.
Sarah tracked her last three menstrual cycles by counting the time from the first day of one period, to the day before the next period. Your most fertile days are the three days leading up to and including the day of ovulation. Some women have very irregular cycles or find it difficult to work out an average cycle length. This can make it hard to work out when ovulation happens. Eggs and sperm need to come together at the right time for fertilisation to happen to create an embryo.
If you're trying to get pregnant, timing is everything. Dr Karin Hammarberg explains how to work out when you are ovulating and the right time to have sex to improve your chance of pregnancy. If a woman has sex six or more days before she ovulates, the chance she will get pregnant is virtually zero.
Some have cycles as short as 21 days and others as long as 35 days. In fact, in one study , only about 30 percent of participants had their fertile window fall within days 10 to 17 of their cycle.
Only 10 percent had ovulation fall exactly 14 days before their next period. Stress and diet can also impact when ovulation occurs, as well as medical conditions such as polycystic ovary syndrome PCOS and amenorrhea. Menstrual cycles can also be more irregular during adolescence or perimenopause. But if your cycle length varies from month to month, it may be helpful to use a backup birth control method. This can provide a more reliable view of your fertile window.
An egg only lives for about 24 hours after being released from your ovary, and sperm can only live for up to five days inside the body. This will give sperm time to reach the fallopian tube and meet the egg there. After that, if no sperm has fertilized the egg, it will dissolve. The timing would have to be perfect for the egg and sperm to reach each other in time.
This is more likely with people who have a shorter-than-average cycle, because ovulation occurs more frequently. However, you may experience some spotting during early pregnancy. One study found that 14 out of participants experienced one day of vaginal bleeding in the first eight weeks of pregnancy. Furthermore, 15 percent to 25 percent of people may experience spotting during the first three months of pregnancy. Taking note of the timing and any other symptoms present can help you differentiate between typical menstruation and pregnancy-related spotting.
Implantation bleeding usually occurs 6 to 12 days after conception. This light spotting usually only lasts 24 to 48 hours and is generally much lighter than the average period. You may also experience spotting as a result of increased blood flow in the cervix.
This type of spotting is most common after sex , a Pap test , or a pelvic exam. If you had unprotected sex and want to avoid pregnancy, take emergency contraception EC as soon as possible. There are two main types — the copper IUD and the hormonal EC pill — and they can both work up to five days after unprotected sex.
The pill delivers a high dose of hormones to delay ovulation or prevent a fertilized egg from implanting to the uterus. As a general rule of thumb, EC pills may be less effective for people who have a higher body mass index BMI. Talk to your local pharmacist or other healthcare provider about which EC option is right for you. But if you can wait a little longer, taking the test one week after the date of your missed period may produce the most accurate result. This will allow your body to develop high enough human chorionic gonadotropin hCG levels to be detected by the test.
Then reach out to a medical provider to confirm the results. Ovulation and the fertile window can change from cycle-to-cycle, but they may also alter with age. Fertility naturally begins to decline in females from 35 years of age onward. Some medical conditions, such as endometriosis or polycystic ovary syndrome, also make conception more difficult. Birth control pills aim to prevent unintended pregnancy. The pill prevents pregnancy by releasing synthetic hormones that stop ovulation from occurring and the uterus lining from thickening.
So, even if the ovaries do release an egg, a fertilized egg would be unable to implant in the wall of the uterus. The pill also thickens cervical mucus, making it harder for sperm to reach an egg.
According to the CDC , the pill is more than 99 percent effective with perfect use but only 91 percent effective with typical use. This means that, with typical use, around 9 out of women would become pregnant in a year of taking the pill.
Women who track their fertile window with the aim of getting pregnant should see their doctor for preconception planning. As well as identifying barriers to conceiving, a doctor can advise on the use of folic acid or prenatal supplements to encourage a healthy pregnancy. Women under 35 years of age should see their doctor if they do not conceive after a year of trying.
Those over 35 years of age should seek medical advice after 6 months of trying to conceive. Anyone who has irregular cycles or does not appear to ovulate should also speak to their doctor.
