What Is A Luteal Phase
The luteal phase is the second half of your menstrual cycle, beginning at ovulation and ending with a new period or pregnancy. This is when you have a huge surge of three important hormones:
- Follicle stimulating hormone: Is released into your bloodstream by the pituitary gland to stimulate ovarian follicles to secrete estrogen and produce a mature egg .
- Luteinizing hormone: Is also released into your bloodstream by the pituitary gland in response to rising estrogen levels. This important hormone triggers the ovarian follicle to release the egg for potential fertilization.
- Progesterone: While estrogen plummets with ovulation, progesterone begins its climb to help nourish and thicken your uterine lining for potential egg implantation. Your progesterone levels will continue to rise if you become pregnant, as it literally helps to pro-gest your fertilized egg.
What Can Cause Pregnancy Tests To Be Wrong
Each type of pregnancy test is designed to detect a set minimum level of hCG. This is why pregnancy test manufacturers advertise the way they do: Know four days sooner, or Accurate up to six days before a missed period. However, while home pregnancy tests are quite accurate many boast a 99 percent detection rate based on laboratory testing results marketing claims can be misleading. For example, a 99 percent detection rate means a test can detect hCG 99 percent of the time on the day a woman misses her period. These statistics also assume that women are testing at the optimal time, following all instructions, and fully understanding how to interpret the results.
In reality, its not that easy. Some studies suggest that up to 1 in 4 tests could be misinterpreted, which has led some companies to switch from using the presence of lines or colors to indicate a positive result to using actual words such as yes, no, pregnant, or not pregnant for clarity.
When a test result is inaccurate, its either a false negative or a false positive . Several factors can cause false negative results:
Having too dilute urine after drinking a lot of water or testing later in the day.
Testing too soon when there has not been enough time for an early pregnancy to implant and start producing hCG.
Using a pregnancy test that doesnt detect lower levels of hCG. You can check the package insert for more information about the level at which the test will be positive.
Tracking Your Temperature To Determine Phase
To determine if youve ovulated and are in the luteal phase, you can try tracking your basal body temperature . This is your temperature right when you wake up, before you even get up to use the bathroom or brush your teeth.
During the first part of your cycle, your BBT will likely hover between 97.0 and 97.5°F. When you ovulate, your BBT will go up because progesterone stimulates heat production in your body.
Once youre in the luteal phase of your cycle, your basal body temperature should be about 1°F higher than it was during the follicular phase. Look for this temperature bump to tell you that youve ovulated and entered the luteal phase.

How Many Days Does It Take To Get Your Period
The average menstrual cycle is about 28 days. This means that about 28 days pass between the first day of your period and the first day of your next period. Not everyone has this textbook cycle, though. You may find that your periods typically occur every 21 to 35 days. Periods that are closer together or further apart arent always cause
The Ovulation Cycle Divided Into Two Parts:
- The first part of the cycle is called the follicular phase. This phase starts the first day of the last menstrual period and continues until ovulation.
This first half of the cycle can differ greatly for each woman lasting anywhere from 7 days to 40 days.
- The second half of the cycle is called the luteal phase and is from the day of ovulation until the next period begins. The luteal phase has a more precise timeline and usually is only 12-16 days from the day of ovulation.
This ultimately means that the day of ovulation will determine how long your cycle is. This also means that outside factors like stress, illness, and disruption of normal routine can throw off your cycle which then results in changing the time your period will come. So the old thought that stress can affect your period is only partly true. Stress can affect your ovulation which ultimately determines when your period will come, but stress around the time of an expected period will not make it lateit was already determined when it would come 12-16 days earlier!
Fertility Awareness is one way to track when ovulation occurs, and it includes noticing the changes in cervical mucus and using a basal thermometer. Cervical fluid will change to a wet, slippery substance that resembles egg whites just before ovulation occurs and until it is over. A basal thermometer helps track a body temperature rise, which signals that ovulation has just occurred.

Women should be aware that if they have an irregular period, it can make the ovulation days difficult to determine. Said Dr. Martinelli. When examining fertility, its important to realize that an egg can survive for about 24 hours after ovulation, and sperm can live inside a womans body for three daysthough sometimes its possible for them to survive for five days.

What Happens During Ovulation
Ovulation is the release of an egg from the ovaries. A woman is born with all her eggs.
Once she starts her periods, 1 egg develops and is released during each menstrual cycle. After ovulation, the egg lives for 24 hours.
Pregnancy happens if a man’s sperm meet and fertilise the egg. Sperm can survive in the fallopian tubes for up to 7 days after sex.
Occasionally, more than 1 egg is released during ovulation. If more than 1 egg is fertilised it can lead to a multiple pregnancy, such as twins.
A woman can’t get pregnant if ovulation doesn’t occur. Some methods of hormonal contraception such as the combined pill, the contraceptive patch and the contraceptive injection work by stopping ovulation.
Negative Test But Feel Pregnant
Speak to your healthcare provider if youve taken a pregnancy test that has come up negative, but you are experiencing symptoms of early pregnancy such as:
- Breast tenderness
-
High chance of a false negative result if pregnant
-
Expense of repeated tests, if necessary
-
Not accurate with hCG trigger shots

Your Follicular Phase Is Considered Plastic Compared To Your Luteal Phase
That means it can commonly change in length, from cycle-to-cycle. If you know the length of your typical luteal phase you can count backwards to get an idea of when you ovulated. Changes in the length of your cycle are usually pinpointed in the follicular phaseâthe time it takes a follicle to reach the point of ovulation.
Itâs common not to ovulate on a regular basis when you first start menstruating. Itâs also common to have irregular ovulation just after pregnancy and breastfeeding, and during the years approaching menopause.
How To Predict When Menstruation Will Occur Next
Now, you can calculate your period cycle length and know if its regular or not. If your period cycle is 28 days and regular, count forward 28 days from the first day of last period to get your expected next period.
Lets say your period is regular and comes every 28 days. If today is 1st of March and your period started now, you can predict your next period to start on the 29th of March. Easy, right?

Whether you want to conceive or add an extra layer of protection to your birth control method start by using these tips to calculate when you could become pregnant.
Treatment For A Luteal Phase Defect
Effective treatment for luteal phase defect is not clear. That said, you should bring any concerns you have about your menstrual cycle to your doctor. They might want you to try certain treatments, including:
- Address underlying conditions. For example, if you have a thyroid condition it could affect your menstrual cycle and fertility. Your doctor would want to start by treating any condition that could be causing problems with your periods or fertility.
- Boost ovulation with fertility drugs. This treatment can strengthen the corpus luteum and could lead to a healthier luteal phase.
- Progesterone supplementation. This treatment is highly controversial, as it is not clear whether progesterone supplements can improve fertility or reduce early miscarriage. Research has indicated that supplemental progesterone might be beneficial for women who have had three or more miscarriages.
- hCG injections. Low doses of hCG can be given through the luteal phase, but progesterone supplementation is more common and has fewer side effects.
Your doctor might prescribe progesterone injections or progesterone suppositories if you are undergoing IVF treatment. Progesterone supplementation has been shown to improve the luteal phase and improve pregnancy outcomes with IVF.

Symptoms After Ovulation If Youre Not Pregnant
The symptoms you may experience during your menstrual cycle after ovulation can look very similar to those of early pregnancy. Some of the symptoms you may experience if youre not pregnant include breast pain and cramping.
Breast Pain
This familiar pregnancy symptom can be confusing since it also happens for many women in the weeks leading up to your period. Breast swelling and tenderness can occur in the days past ovulation as estrogen and progesterone levels fluctuate. Estrogen causes breast ducts to enlarge and progesterone contributes by causing the milk glands to swell. So, as these hormones increase in the second half of your menstrual cycle, your breasts may start to feel sore.
Leading up to your period, you may experience a dull, heavy pain accompanied by tenderness or feelings of fullness. But since these symptoms are tied to hormone levels, the pain usually improves during your period or right after as progesterone levels go back down.
Cramping
Cramping of any kind in the abdominal region can be uncomfortable, but many women experience this every month with their menstrual cycle making it hard to tell whether this is a sign of pregnancy or another period. As confusing as they can be, there are subtle differences between the two. In most women, period cramps originate in the uterus and can range from mild to intense or severe while implantation cramps are usually described as milder and less intense.
Understanding Your Ovulation Calculator Results
There are many ovulation calculators available today that estimate when your fertile days will occur. These calculators are a form of calendar method and work on average data without reading anything about your personal hormone levels. However, none of us are average:1. Cycle lengths vary from woman to woman and cycle to cycle – in fact nearly 52% of menstrual cycles vary by 5 or more days12. The timing of ovulation can vary by a few days, even in regular cycles.
Should we have intercourse every day I am fertile?
Professor William Ledger
Sperm that are stored within the testicles for too long accumulate damage to the DNA and are less fertile. With couples who have frequent intercourse, the man will have a lower sperm count per ejaculation but the sperm will be more fertile. If you are trying to conceive then try to have intercourse at least every other day around the time of ovulation.

Ovulation: How Many Days After A Period Is It
If your cycle is always exactly 28 days long, ovulation occurs about 14 days after the first day of your period. But according to the research, if your cycle is always exactly 28 days long, youre practically a unicorn.
One study measured the cycle lengths of women who identified as having regular menstrual cycles, and found 46% of them actually had cycles that varied within a 7 day range. An additional 20% had cycles that varied within a 14 day range . Couple that with the ~18% of women who identify as having irregular menstrual cycles , and its safe to say that most peoples cycles are not always exactly 28 days long.
Although cycles lasting anywhere between 21 and 45 days are considered normal , you cant accurately predict your ovulation timing by simply counting 14 days after your period starts if you deviate from the average 28 day cycle.
More detective work is needed, and this article is your guide. It covers:
- Why ovulation timing depends on the length of your cycle
- How to know when ovulation occurs if your cycles are longer or shorter than 28 days
- Why ovulation isnt just a fertility concernits a big deal for your period, too!
Length Of Your Menstrual Cycle
Your menstrual cycle begins on the first day of your period and is a critical component in determining when you can get pregnant. Most women have a 28-day cycle from the first day of one period to the first day of the next, but it can vary. Some have cycles as short as 21 days, for example. Technically, your cycle is considered regular if you have your period at least every 24 to 38 days, but that degree of variation can make estimating your fertility period challenging.
If you skip periods entirely or have cycle lengths that fall outside the regular range or change significantly from month-to-month, then you have what is known as an irregular cycle. Unfortunately, that will make it harder to pinpoint when you are likely to ovulate. If you are having difficulty conceiving and want to calculate the best estimate for when you could become pregnant, you may have to track your periods for a few months to determine an average length or some sense of a pattern for your cycle.
