Late Period Negative Pregnancy Test: Causes And Is It Common
Many people who miss a period will take a test to check for pregnancy. If the pregnancy test is negative, various conditions and factors may be responsible for the lack of menstruation.
The ovaries release an egg during ovulation, approximately every 28 days. If no sperm fertilizes the egg, a persons period will usually start about 14 days later.
While a missed period is one of the first signs of pregnancy, there are various other reasons why it can occur.
Menstrual irregularities, such as missed or late periods, occur in of women of childbearing age. They can result from a range of conditions besides pregnancy, including hormonal imbalances, hormonal birth control, stress, weight loss, trauma, and certain health conditions.
This article discusses what can cause a person to miss their period and how common this is.
Amenorrhea is the absence of menstruation during a persons reproductive years. Someone may have this condition if they miss their period for 3 months in a row or have not had their first period by the age of 15.
This condition affects 34% of women.
Amenorrhea usually happens when the ovaries stop making enough of the hormone estrogen. A range of factors can cause a lack of estrogen.
Several health factors and conditions can cause a person to miss their period.
How Accurate Is The Due Date
The pregnancy calculator gives you an approximate due date. It is worked out by adding 280 days to the first day of your last menstrual period. This is based on a 28-day cycle but is adjusted for longer or shorter cycles.
Your period and ovulation are counted as the first 2 weeks of pregnancy. If you have the baby on your due date, your baby has been growing for 38 weeks, not 40, but you are still classed as 40 weeks pregnant.
Remember that only around 5% of babies are born on their due date so its just an estimation.
Weight Gain During Early Pregnancy
Weight gain becomes more common toward the end of your first trimester. You may find yourself gaining about 1 to 4 pounds in the first few months.
Calorie recommendations for early pregnancy wont change much from your usual diet, but they will increase as pregnancy progresses.
In the later stages, pregnancy weight often shows up in the:

Pregnancy is most commonly measured gestationally from a woman’s last menstrual period to birth. This period is known as gestational aging.
Youre In Early Menopause
Early menopause, also known as premature ovarian insufficiency, happens when your ovaries stop working before you turn 40.
When your ovaries are not working the way they should, they stop producing multiple hormones, including estrogen. As your estrogen levels drop to all-time lows, you will begin to experience the symptoms of menopause.
Late or missed periods may be an early sign. You may also experience:

First Day Of Last Period
Most pregnancies last around 40 weeks , so typically the best way to estimate your due date is to count 40 weeks, or 280 days, from the first day of your last menstrual period . You could also subtract three months from the first day of your last period and add seven days.
The first day of your LMP is how most health care providers estimate a baby’s due date. But remember, it’s only an estimated due date, not a deadline for your baby to arrive. Just 4 percent of babies are born on their estimated due date.
What Is My Due Date
Your due date, also known as your estimated date of delivery, is the approximate date your labor might begin. Your estimated due date is commonly calculated by adding 280 days to the date of the first day of your last period, using Naegeles rule. This may vary if you have irregular periods.
It’s worth noting that although predicted due dates are commonly calculated at 280 days, a baby is born on its predicted due date just 5% of the time. 2 A 2020 study published in the International Journal of Obstetrics & Gynaecology suggests a number of factors that can influence the length of your pregnancy, including ethnicity, height, variations in the menstrual cycle, the timing of ovulation, parity and maternal weight. It is for this reason that calculations using Naegeles rule can be considered as an estimate and not a definitive date. 3

When Is The Best Time To Take Pregnancy Test
If youre trying to get pregnant, the best time to take a pregnancy test is one week after youve missed your period. Why? Because this is really the best way to prevent a false negative result result.
Home pregnancy tests can be used as early as the first day after your first missed period in women with regular/predictable monthly menses. If you have irregular periods, you can administer a test 14 days after intercourse, since you likely cant pinpoint your exact time of ovulation.
Pregnancy tests detect a hormone called human chorionic gonadotropin , which is produced in early pregnancy. The production of this hormone begins slowly and increases as the pregnancy grows. Standard urine pregnancy tests will detect the HCG level when it reaches 20-50 milliunits/milliliters.
If you take a test too soon , the levels of HCG may not be high enough to detect a pregnancy and it could cause a negative result, even though you’re actually pregnant.
I advise my patients to wait at least one day after you miss your period. If you wait one week after a missed period, the chance of a false negative is very low if you have a normal monthly menstrual cycle.
What Is The Last Menstrual Period
The LMP is the date of the first day of the last menstrual period you had before conceiving. It is the first day that your last menstrual cycle begins when you see bright red blood, not just a little brown spotting. You should keep track of your LMP each month, either with an online calculator or just by recording it on a calendar each month. That is the date you use when entering the LMP on an online period calculator.
Whether you are trying to get pregnant or not trying to get pregnant, keeping track of your menstrual periods is vital. Besides pregnancy, missing a menstrual period could also be a sign of other issues like missed ovulation.

/5when Is The Right Time To Take The Test
The best time to take the pregnancy test is after your period is late. You can take the test from the first day of your missed period. Some test kits show positive as early as 4 or 5 days before your period is due. Taking the test after a missed period can help you avoid false negatives and the false positives of very early miscarriages. If your menstrual cycle is irregular then wait for 35 to 40 days before taking the test for an accurate result.
Things That Delay Your Period
A missed period is often the first sign of pregnancy, but there are other reasons for lateness, too. Here are some other factors that can delay your monthly flow:
Extreme diet and exercise
A healthy diet and regular exercise can do wonders for your health. But if you overdo it, you might say bye-bye to your periods, at least temporarily.
Athletes who train really hard or who dont get enough calories may stop menstruating, Dr. Higgins says. Its the bodys way of telling you that it doesnt have enough resources to support a pregnancy.
When your periods stop due to weight loss, diet or exercise, youre experiencing secondary amenorrhea. This means you previously had periods, but they have stopped. Secondary amenorrhea might happen to you if you:
- Eat an extreme, calorie-restricted diet.
- Have an eating disorder, such as anorexia or bulimia.
- Lose a lot of weight in a short amount of time.
- Undergo hardcore exercise training, such as for a .
Polycystic ovary syndrome
PCOS is a hormonal imbalance that interferes with the release of an egg . When you dont ovulate, you usually dont have a period. Many people with PCOS have irregular, late or missing periods. Other symptoms of PCOS include:
- Excess facial or body hair.
- Weight gain or trouble losing weight.
Doctors diagnose PCOS by checking your symptoms and performing medical tests when needed. Medication and lifestyle changes can help manage the symptoms.
Some examples of major stress include:

Treatments For A Late Period And Pregnancy
In general, if youve missed a period and you know youre not pregnant, you dont need specific treatment or care. However, if you were having a regular cycle and youve stopped, if youre experiencing bleeding at unexpected times, if its been more than 45 days since your last period, and if you have additional symptoms that point to other concerns, your doctor will likely look into treatment options. Depending on the cause, your doctor may prescribe hormone therapy like birth control pills or other medication, or they might be able to suggest lifestyle changes to help you have a regular period cycle.
If your late period is a sign of pregnancy, your doctor can help you come up with a treatment plan to be sure you receive the proper care and regular checkups throughout your pregnancy.
/5the Right Time To Take The Test
Studies show that taking the pregnancy test in the morning gives you a more accurate result. Thats because the urine is more concentrated in the morning, so the hCG concentration is higher. This means you are more likely to get a positive result if youre pregnant. This is more effective when your period is late. The chances of false-negative are high when you take the test before your monthly period cycle and you are drinking a lot of water and your urine is diluted.

Why Pregnancy Is Counted From The Last Menstrual Period
Pregnancy is counted from a women’s last menstrual period because the start of a period is easily observable and usually known to a woman whereas the date of conception is much less likely to be known.
Historically, the first day of the last menstrual period became the date from which pregnancy is counted even though conception occurs about two weeks later.
The LMP formula is good for working out an initial age of pregnancy but ultrasound is more accurate. The age of pregnancy may be revised following your ultrasound scan.

Why Is It Important To Know Your Exact Pregnancy Week
How far along you are determines nearly everything in your pregnancy including blood tests, ultrasound examinations, and more importantly when you can expect your baby to be born. It also helps you identify certain situations to learn what is normal and when to have procedures done. What is normal at 26 weeks may not be normal at 32 weeks. Also, tests that should be done at 20 weeks but are done at 16 weeks could be interpreted incorrectly.
How To Prevent A False Negative Result
The number one cause of a false negative test is taking the test too soon after you conceive. Also, if you dont follow the test instructions carefully, it could affect your result.
Urine, even in women who drink large amounts of water, should still yield a positive result. But urine shouldnt be diluted with water before taking a test. A good time to take the test is in the morning when you first wake up.
If a test is negative in a woman who suspects shes pregnant or if she has irregular cycles, she should repeat the test in one week.
Your Body At Week 4 Of Pregnancy
You may not notice any differences in your body or feel any symptoms at 4 weeks pregnant. For most women, particularly those with a regular menstrual cycle, the first sign of pregnancy will be a missed period. The best way to confirm conception is with a pregnancy test, either at home or at a clinic.
Some women may notice very slight bleeding, or spotting, around the time that implantation occurs. Although you wont be able to tell, inside your womb the amniotic sac and placenta will be developing and will later provide oxygen and nourishment to your embryo.
Once you know that youre pregnant, you can start the clock! Your pregnancy is considered to have begun from the start of your last period and a normal term is 40 weeks from this point. Note that your healthcare provider may modify this start date after completing an ultrasound scan later on in your pregnancy this provides a more reliable and consistent way to track your dates.

You will likely miss your next period 4 weeks after conception. If you typically have an irregular period, youll want to take a pregnancy test to confirm.
Most home tests can detect hCG as soon as 8 days after a missed period. A pregnancy test will be able to detect hCG levels in your urine and show if you are pregnant.
Morning Sickness & Digestive Issues
At four weeks pregnant, you may or may not be experiencing morning sickness or other digestive issues such as nausea and headaches or diarrhea. Not all women have issues with their digestive system, while others can become severely ill, as did Kate Middleton, with a condition called hyperemesis gravidarum.
Hyperemesis gravidarum is rare only 5% of pregnant women will suffer from this disorder. However, if you are experiencing severe nausea, vomiting, diarrhea, or weight loss, speak with your OB-GYN.
