Although pregnancy tests and ultrasounds can be the only way to tell if you are pregnant, there are many other signs and symptoms that you should look out for. The earliest signs of pregnancy are more than a missed period. These may include morning sickness, nausea, and fatigue.
Though it may sound odd, your first week of pregnancy is based on the date of your last menstrual period. Even if you aren’t pregnant, your last menstrual period will be considered week 1.
The expected delivery date is calculated using the first day of your last period. The first few weeks in which you don’t have symptoms count towards your 40-week gestation.
|Signs and symptoms||Timeline (from the missed period)|
|Mild cramping and spotting||Weeks 1 through 4|
|Missed period||Week 4|
|Fatigue||Week 4 or 5|
|nausea||Week 4 – 6|
|Tingling or aching breasts||Week 4 – 6|
|frequent urination||Week 4 – 6|
|Bloating||Week 4 – 6|
|motion sickness||Week 5-6|
|Mood swings||Week 6|
|Temperature changes||Week 6|
|High blood pressure||Week 8|
|Extreme fatigue and heartburn||Week 9|
|faster heartbeat||Week 8-10|
|Breast and nipple alterations||Week 11|
|noticeable weight gain||Week 11|
|pregnancy glow||Week 12|
From week 1 to week 4, everything is still happening on a cellular level. The blastocyst, a liquid-filled group of cells that is created by fertilization, will become the baby’s organs.
The blastocyst, which is the lining of your uterus, will implant within 10-14 days (week 4) from the time you are conceived. This can cause implantation bleeding, which may be mistaken for a light period.
These are signs that you might have implantation bleeding.
After implantation is complete your body will start producing human chorionic Gonadotropin (hCG). This hormone is necessary for maintaining a pregnancy. This hormone also tells the ovaries not to release mature eggs every month.
Your next period will be missed four weeks after conception. To confirm if you are having an irregular period, you will need to have a pregnancy test.
Most home tests can detect hCG as soon as eight days after a missed period. A pregnancy test can detect hCG in your urine and tell you if you’re pregnant.
A higher basal body temperature may also be a sign of pregnancy. Exercise or hot weather can also cause your core temperature to rise more quickly. You’ll need more water, and to exercise with caution during this time.
You can experience fatigue at any stage of pregnancy. This is a common symptom in early pregnancy. This can cause you to feel tired and increase your progesterone levels.
Your heart might start pumping harder and faster around weeks 8-10. Palpitations and arrhythmias are common in pregnancy. It is usually due to hormones.
The fetus causes an increase in blood flow later in pregnancy. Management should begin before conception. However, if you have a heart condition, your doctor may be able to help with low doses of medication.
Between weeks 4 and 6, breast changes may occur. Hormone changes can cause tenderness and swelling in breasts. After a few weeks, your body will adjust to the hormones and this condition should disappear.
Around week 11, breast and nipple changes may also be a possibility. Your breasts will continue to grow due to hormones. The area around your nipple, called the areola, may become darker and larger.
If you’ve had bouts with acne before your pregnancy, you may also experience breakouts again.
Your estrogen and progesterone levels will be high during pregnancy. This can cause you to be more reactive or emotional than normal and affect your mood. Pregnancy mood swings can cause depression, anxiety, irritability, and euphoria.
Your body increases the amount of blood that it pumps during pregnancy. This causes your kidneys to process more fluid than usual. This results in more fluid in the bladder.
Bladder health is also affected by hormones. It is possible to find yourself using the toilet more often or accidentally leaking.
Similar to symptoms of a menstrual period, bloating may occur during early pregnancy. Bloating may occur due to hormonal changes that can slow down your digestive system. You may feel constipated and blocked as a result.
Feelings of abdominal bloating can also be caused by constipation.
Morning sickness and nausea usually start around weeks 4-6. It’s sometimes called morning sickness but it can happen at any time of the day or night. Although it is not known what causes morning sickness and nausea, hormones could play a part.
Many women suffer from mild to severe morning nausea during the first trimester. Morning sickness can be more severe towards the end of the first trimester but it usually gets less severe as you move into the second trimester.
Normal or high blood pressure will decrease in most cases during pregnancy. Because your blood vessels dilate, this can also lead to dizziness.
High blood pressure as a result of pregnancy is more difficult to determine. Hypertension almost always develops within the first 20 week. Hypertension can develop in early pregnancy but may also occur before.
To establish a baseline reading for normal blood pressure, your doctor will measure your blood pressure at your first visit.
The symptom of smell sensitivity in early pregnancy is often self-reported. The first trimester is not known to show any scientific evidence of smell sensitivity. It may be important because smell sensitivity can cause nausea and vomiting. You may feel a strong dislike for certain foods.
One reviewTrusted Source looked at reports from 1922 to 2014 about the relationship between smells and pregnancy. According to the researcher, pregnant women tend to rate odors more intensely in their first trimester.
Weight gain becomes more common toward the end of your first trimester. In the first few months, you may gain anywhere from 1 to 4 pounds. While the calorie requirements for early pregnancy will not change from your normal diet, they will increase as your pregnancy progresses.
In later stages of pregnancy, the weight of a woman’s baby can often be spread between:
Hormones can relax the valve between your stomach esophagus. This allows stomach acid to leak, causing heartburn.
People may start to say that you have the “pregnancy glow.” This is due to increased blood volume combined with higher hormone levels pushing more blood through your veins. This causes your body’s oil glands work overtime.
Your skin will appear more radiant and glossy due to the increased activity in your oil glands. On the other hand, you may also develop acne.
As you enter the second trimester, many of the symptoms and body changes that you experienced in the first trimester of pregnancy will begin to disappear. Discuss any symptoms that are affecting your daily life with your doctor. You can work together to find comfort and relief for your pregnancy.
