Earliest Signs of Pregnancy after 1 Week

Please share this one!

Broadly speaking about pregnancy, early signs and symptoms of the condition is one of the most frequently asked questions. What is the most common early sign of pregnancy after 1 week? There is no certain answer since the symptoms vary from woman to woman. But in general, there are some common ones that may signal your early conception.

Overall, there is a wide variety of signs and symptoms after 1 week of conception. Some women experience a few symptoms or even none symptoms, while others do have a lot of symptoms. Even if you are pregnant for the second time, your early symptoms could be different to your first pregnancy.

In the first week after conception, it’s difficult to use your late period to predict your pregnancy (particularly if you have irregular periods). The table below (credit to countdowntopregnancy.com) estimates some common and less common pregnancy symptoms 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 probably the most common symptom early pregnancy after 1 week.

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

Also, it’s important to understand that having some of pregnancy symptoms doesn’t always mean you are pregnant. All symptoms mentioned in that chart (including fatigue) are vogue. They don’t tell you that you are definitely pregnant since they also can be attributed by other factors.

But if you experience some of these symptoms while you’re trying to get pregnant with your partner, it’s likely that you’re pregnant — use a home pregnancy test or take a clinical pregnancy test (if necessary) for more accurate diagnosis!


Most pregnant women have increased fatigue. In general, it usually starts to affect your in the first trimester. Even you may already notice it in the 7-11 days after conception.

Hormonal changes during pregnancy are one of the main reasons of why you’re likely to feel tired easily as your pregnancy progresses.

Another reason probably is the increased blood distribution to supply more nutrients and O2 (oxygen) for the growth of the fetus. To respond this transition, your heart need to pump more blood and work harder.

Also, sometimes it may have to do with the decreased level of your blood sugar especially if you have diabetes.

What should you do? Listen to changes of your body – you are the perfect one that completely understands your situation. Get plenty of sleep and rest!

Any stimulants (e.g. caffeine and alcohol) are not recommended during pregnancy to keep safe! Also, have regular exercise and stay on a balanced diet!

Abdominal cramps

In early pregnancy, there are a lot of changes that occur for preparing the growth of the fetus. And it is also reasonable that abdominal cramps are common in this period. This symptom may occur when the embryo implants into the wall of your uterus, which usually occurs about 6 to 12 days after conception.

What does it feel like? It is also often described as a feeling like bubbles /tingles, little twinges /pinching like pokes, quick sharp cramp, or sometimes may be mistakenly identified as a cramp of PMS.

Flatulence and abdominal bloating

Decreased digestive process usually occurs when you eat a large meal. This would make flatulence and bloating.

Anecdotal reports about decreased digestive process in early pregnancy are also ample.

The increased pregnancy hormones may affect the elasticity of certain muscles. It may relax the muscles of your digestive tract, too. And this would slow the digestive process, giving more time for bacteria in digesting the foods. As a result, you’re likely to have flatulence and abdominal bloating (gas).


It could be a consequence of the increased production of progesterone hormone. This may cause the decreased performance of your body to support your disks and ligaments.

Other factors that may factor into your backache are lack of sleep at night. But if your backache gets worse (it doesn’t improve to lifestyle measures), see a doctor promptly!


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

The exactly cause for this morning sickness is still not known! But again, increasing pregnancy hormones (such as hCH and progesterone) are thought to play a role.

In several cases, nausea and vomiting are followed with an increased sensitivity to certain smells. You may be more sensitive to cooking foods, tobacco smoke, coffee, or even certain colognes /perfumes – these smells may provoke your nausea and vomiting.
