Tests and symptoms during the first week of pregnancy

The majority of people don’t show any signs of pregnancy at week one, but others may show signs as early as week five or six after sexual activity, including exhaustion, breast tenderness, and minor cramps.

Pregnancy is usually measured by medical professionals starting on the first day of the last menstrual cycle. An approximate pregnancy due date can be found by counting the first week of the last menstrual cycle, even though the person is not genuinely pregnant at this stage.

Pregnancy week 1 is defined in this article as the actual first week of pregnancy, beginning one week following fertilization.

One of the most common signs of an early pregnancy is generally the missing menstrual cycle.

First week symptoms

When an ovary produces an egg (ovulation) and a sperm fertilizes it, this process is known as conception, or fertilization. This can occur anywhere from 14 days to 28 days following the onset of a normal menstrual cycle, though individual differences may occur.

After fertilization, implantation usually starts 5-7 days later. This is the point at which the fertilized egg adheres to the uterine lining. The uterine wall’s blood vessels may be broken by the egg’s movement, which could result in mild bleeding and cramps.

First-week pregnancy symptoms

First-week pregnancy symptoms are uncommon (Trusted Source). Every person and every pregnancy is unique, though, and so are the signs and stages of the condition.

Absence of periods

Most of the time, missing or substantially lighter periods are the earliest signs of pregnancy.

Bleeding An early indicator of pregnancy is transplantation bleeding. It differs from the menstrual cycle. Rather, there is mild bleeding that may just entail a small amount of pink discharge or a single dab of blood. The period of spotting could be a few hours or several days long.


Mild cramps may also be experienced by people while the embryo adheres to the uterine wall. Some people may get cramping in the lumbar back, pelvis, or abdomen.

There may be a tugging, tingling, or prickling sensation associated with the cramps. Some may have sporadic pain that comes and goes over several days, while others may just have a few mild cramps.

Additional signs and symptoms

Additional signs of an early pregnancy include:

  • breast changes, such as tenderness, swelling, or tingling, or obvious blue veins, nausea with or without vomiting
  • a lot of urinating
  • headache elevated the body’s core temperature
  • stomach bloating or gas
  • exhaustion or weariness agitation or mood fluctuations
  • dietary aversions or desires
  • an enhanced ability to smell
  • mouthfeel of metal

These symptoms are not exclusive to pregnancy. Notably, early pregnancy does not always result in symptoms that are obvious. However, five to six weeks following the first day of their last menstrual cycle is when most people start to experience pregnancy symptoms.

Pregnancy tests are the most reliable technique for someone to determine whether or not they are pregnant.

The ideal time to test for pregnancy

The level of the hormone human chorionic gonadotropin (hCG) in the urine is measured during a pregnancy test. This hormone is exclusive to the pregnant woman. The cells that surround the developing egg and eventually give rise to the placenta release human growth hormone (hCG).

Pregnancy tests should be taken as soon as feasible following a missing menstruation. As early as ten days after conception, a pregnancy test may come up positive. But usually, it takes three weeks or more for the urine to contain enough hCG to result in a positive pregnancy test.

Accuracy of at-home tests

Pregnancy tests are widely accessible over-the-counter (OTC) and online at reasonable prices with high reliability. In just a few minutes, a home pregnancy test can determine whether you are pregnant; most of them claim to be nearly 99% accurate.Trusted Source.

The capacity of the test to identify an arbitrary amount of intact hCG given to urine samples from non-pregnant individuals supports the manufacturers’ 99% claim for these kits. For many people who have recently missed a menstrual cycle, the test will not be sensitive enough to identify pregnancy.

The ideal time to take a pregnancy test is one weekTrusted Source following a missing period in order to help ensure an accurate result. A pregnancy test yields positive or negative findings.

Negative results

If a person takes a pregnancy test less than one week after missing a period, the result may be negative, even if the person is pregnant.

If a person believes they are pregnant despite a negative test result, they should take another test after one week. To avoid receiving a false negative result, check the pregnancy test’s expiration date and carefully follow the printed instructions.

A person can also have a blood test to see if they are pregnant. This test determines the presence of hCG in the bloodstream. The blood test can produce a positive result a few days earlier than the pee test, but the findings can take up to 48 hours to arrive from the lab.
