Earliest Signs of Pregnancy after 1 Week

When people talking about pregnancy, the early signs that may occur after 1 week are one of the most frequently asked questions. Unfortunately there is no certain answer for this case. In other words, the symptoms vary from women to women. However, there are some earliest signs that are believed can be used to predict that you are being pregnant.

You can find a lot of articles on internet that discuss about the early symptoms of pregnancy, but you should clearly understand that having some of these symptoms doesn’t mean you are definitely pregnant. The best idea for the clearly answer of whether you are pregnant or not-pregnant is by using home pregnancy test or even with a clinical pregnancy test if necessary for more accurate result!

Overall, there is a wide variety of signs after 1 week. Some women experience few /very few / or even none symptoms in their first week of trimester, while others can experience a lot of symptoms. Even if you are pregnant for the second time, your early symptoms may also be slightly different /very different to your first pregnancy.

In the first week after your conception, it’s difficult to use your late period to predict your pregnancy (particularly if you are a woman who has irregular periods). The table below (credit to countdowntopregnancy.com) estimates some common and less common signs that may occur after 7 days of conception.

The chart suggests that there is always possibility of ‘not-pregnant’ for each symptom. According to this chart, exhaustion /fatigue is the most common sign that may occur after 1 week of conception.

Fatigue takes about 20.3 percent of ‘pregnant label’ and 6.9 percent of ‘non-pregnant label’. In other words, about 27.2 % of all participants who trying to get pregnant experienced fatigue after 1 week of ovulation – which about 20.3 % were eventually pregnant and 6.9 % were not pregnant.

So again, always remember that all symptoms mentioned in that chart (including for fatigue) are categorized into vague /uncertain signs of pregnancy. The following are more detailed explanations about these symptoms.


Most pregnant women will have increased fatigue, and it usually will be clearly noticed in the first trimester. You may notice it clearly in the 7-11 days after conception.

Hormone changes during pregnancy are one of the major keys /reasons of why pregnant women are more likely to get fatigue easily and experience other pregnancy symptoms.

Another reason is the increased blood productions to distribute more nutrients and O2 (oxygen) for the growth of fetus. To respond these transitions, your hearts also need to pump more blood and therefore it needs to work harder. Furthermore, sometimes the decreased level of your blood sugar may also cause excessively fatigue.

If you experience fatigue or even excessively fatigue, what you should do? Listen to changes of your body – you are the perfect one that completely knows your condition. Get plenty of rest! If you have poor sleep, get back your healthy sleep cycle!

Any stimulants (particularly such as caffeine and alcohol) should be consumed in moderation or avoid it if necessary during pregnancy to keep safe! Don’t forget to have regular exercise and stay on a balanced diet.

Dull pressure /mild cramps in the abdomen

In the early pregnancy, there are a lot of changes that occur for preparing the growth of fetus. And therefore, it is reasonable that cramps are very normal in the early weeks of trimester. This symptom usually also occurs when embryo implants in the wall of your uterus (about 6 to 12 days after conception).

In addition, this symptom is also often described as feeling like bubbles /tingles, little twinges /pinching like pokes, quick sharp pains, or period cramps /PMS.

Flatulence and bloating

The increased pregnancy hormones can affect the elasticity of certain muscles of your body. It can relax the muscles of your digestive tract. And this condition can slow the digestive process, which then can give more time for bacteria in digesting the food that you eat. As a result, there is more time for more fermentation and this can generate more gas.

In essence, your decreased digestive process can lead to bloating, flatulence, and other uncomfortable sensations /more gas in the abdomen. And typically, these problems occur after you got a large meal.


It usually occurs due to the increased progesterone hormone that causes the decreased performance of your body to support your disks and ligaments. Other factors that can lead to backache are lack of night’s sleep or even urinary tract infection. If your backache gets worse, see a doctor promptly for more advice!


This symptom is often associated with a familiar term called ‘morning sickness’. Typically, sometimes it is also followed with vomiting. Nausea & vomiting can occur /strike anytime, but they are usually at worst in the morning.


The exactly answer for the cause of nausea and vomiting is still not known! But again, increasing pregnancy hormones (such as hCH and progesterone) are believed have a significant contribution to cause these symptoms.

In several cases, nausea and vomiting are also followed with an increased sensitivity of certain smells. You may be more sensitive to the smells of certain cooking foods, smoke of cigarette smoking, coffee, or even cologne /perfume – these smells may trigger your nausea and vomiting.
