3rd Month Pregnancy: Symptoms, Baby Development, Tips and Body Changes

When you start your third month of pregnancy, it can be a relief. It means that your first trimester is about to end. If you have been suffering from nausea or vomiting during your first trimester, it may be about to end. Until this month is over though, you will still have a number of 3rd month pregnancy symptoms that you can expect.

3rd Month Pregnancy Symptoms

There are a number of body changes and symptoms that you can expect during the third month of your pregnancy. Some of these symptoms will just be a continuation of your symptoms last month, although new pregnancy symptoms may also develop.

Morning Sickness

One of the most famous pregnancy symptoms is morning sickness. The bad news is that this pregnancy symptom will most likely keep going this month. In most cases, the nausea and vomiting associated with pregnancy are not anything that you need to worry about. There are some instances where women experience hyperemesis gravidarum. This condition can cause severe dehydration and weight loss from the vomiting. An estimated one percent of women who develop this condition end up needing intravenous treatments to fix their fluid imbalance. Luckily, this condition should not cause ongoing problems as long as it is properly treated.

If nausea and vomiting are a problem, there are a few options that you can use to help. Eating a balance high in protein, vitamin B6 and vitamin B1 can help. Try to eat smaller meals more frequently. Acupressure bands may work to alleviate your nausea. Meanwhile, ginger tea or biscuits can help. Doctors may also recommend avoiding strong smells. Brushing your teeth can reduce nausea, and you should make sure to drink plenty of fluids so that you do not become dehydrated.

Weight Gain

While you may still be suffering from nausea and vomiting, you may still start to gain weight. Weight gain helps to show your doctor if your baby is growing. BMI and weight gain varies from woman to woman, so do not worry if you are gaining slightly more or less weight than your friends are. As long as your doctor is not concerned with your progress, it is probably not an issue.


With the changes in your hormones and morning sickness, you might be suffering from fatigue. The changing hormones in your body cause increased levels of sleepiness. Your body has to create extra nutrients for the fetus, and your blood supply is increased. This causes your blood pressure and blood sugar levels to be affected. As a result, you feel fatigued all the time. Emotional triggers and stressful situations can also cause you to feel fatigued. If you are feeling consistently tired, try to get more sleep. During the second trimester, your energy levels should increase a bit.

Frequent Urination

When you are pregnant, your body begins to produce a hormone known as hCG. This hormone has an unfortunate side effect of making you feel like urinating all the time. Unfortunately, you cannot just stop drinking fluids to urinate less often. This could make you become dehydrated, which can be medically dangerous and can also make you feel more fatigued.

Other than hCG, the growth of the baby and your uterus causes extra pressure on your bladder. As a result, you may find yourself going to the bathroom constantly. Some women find that avoiding fluids right before bed helps to reduce their need to urinate at night. While this can make your sleeping patterns easier to maintain, you need to make sure that you are still drinking plenty of fluids during the day.

If you pass blood in your urine, cloudy urine or foul-smelling urine, then go to your doctor. This could be a symptom of a urinary tract infection. If left untreated, it could end up causing a kidney infection.

At the end of the third month of pregnancy, your uterus moves to the pelvic area of your abdomen, This reduces the frequent urination issue. At the same time, the body is trying to provide nutrients that the baby needs to grow. The increased blood supply to the baby can reduce the amount of blood available for the rest of your body. As a result, you may experience dizziness and lightheadedness. Your blood pressure drops and your blood sugar levels are lower than normal. In addition, your hormonal fluctuations can make your gums more likely to bleed.

The good news? By the end of the third month, your chances of having a miscarriage have dropped significantly. Your nausea and vomiting will most likely drop quickly as well. Meanwhile, your breasts will be larger in size with bigger, darker areolas.

Common Pregnancy Concerns at the 3rd Month

Some of your bodily changes at this stage are perfectly normal, although they can be worrisome. We will cover some of the most common concerns that women experience during the third month of pregnancy.

Diet Control

Weight gain is normal during pregnancy and is a sign of a healthy pregnancy. While you may not like the weight gain, don’t try to go on a diet. Your baby needs to have healthy food and nutrients to keep it growing. As long as you eat a healthy diet and avoid eating junk food, it should not be a major problem. Just accept that weight gain is normal and perfectly okay. While you don’t want to deliberately overeat, you need to gain some weight or your child may be born with a low birth weight.

As for the rest of your diet, avoid uncooked meat or unpasteurized dairy products. You should also avoid fish that are high in mercury like swordfish, sharks or mackerel. To prevent food-borne illnesses, make sure to wash your hands and kitchen equipment constantly. Focus on consuming foods that are high in calcium, folic acid and iron.


Bleeding during early pregnancy may terrify you, but it is often not a sign of a problem. While it can sometimes be a sign of a miscarriage, many women experience light spotting or bleeding without a problem. This may happen continuously or for just a few hours. Bleeding may happen right after sex or near when your periods were going to be.

If you have heavy bleeding or cramping, go to your doctor because it could be a sign of a miscarriage. The risk of miscarriage drops significantly after your third month of pregnancy, so you may want until the second trimester to share your good news. As always, call your doctor if you are concerned because heavy bleeding could be a sign of conditions like placenta praevia or an ectopic pregnancy.

Neural Tube Defects or Spina Bifida

This condition happens when the neural tube located around the spine does not close. It can happen because of genetic or environmental causes. Individuals who have parents with this condition have a three to five percent chance of also having it. Eating plenty of folic acid while pregnant can lower this risk.


Now that your baby is growing, you may feel fatigue. Exercise can help lower your fatigue. You have to make sure to do pregnancy-safe exercises, so talk to your doctor. Generally, exercises like swimming, Pilates, walking and cycling will normally be safe. If you experience unusual symptoms like abdominal pain or bleeding, make sure to stop immediately and go to your doctor. If you exercise during pregnancy, it can also boost your stamina for labor.

Your Baby’s Development in the Third Month of Pregnancy

Your baby is finally starting to look like a little human. She is about the size of a peanut and her heartbeat can be heard this month. She is continuing to grow, but her genitals are still in development. Her bone marrow and white blood cells are starting to develop. Her legs, arms and head are continuing to grow, and most of her organs are completely formed.

At this stage, your doctor may check you for bacterial infections or anemia. He or she may listen to your baby’s heartbeat. Blood and urine tests may be given to check your organ function and sugar levels. Your doctor may check for symptoms of edema and measure the size of your stomach.

Getting Ready for Baby

It is time to start preparing your home for babies. Seal electrical outlets with protectors so that the baby will not be unintentionally electrocuted. Start setting aside safe areas to store chemicals, medication and house cleaners. If you have the space, start planning a room for the baby.

For partners, this is the time to be patient. Your girlfriend or wife may have mood swings, food cravings and extreme fatigue. Hormones are the cause, so just be as patient and understanding as possible. Start planning out your financial costs and health insurance for labor. Together, go to the prenatal checkups. Fathers-to-be can start pitching in with the housework or other chores to give the mother-to-be time to rest. While only one person carries the child physically, pregnancy is truly a job for both parents. A supportive partner can make the pregnancy much easier and more comfortable to experience.
