3 Months Pregnant: Your Baby

At the end of your second month of pregnancy, your baby officially becomes a fetus. They’ve already completed the germinal and embryonic stages of development and are gearing up for some major growth.

Developmental Milestones

By the month's end, your baby will be completely formed. All their internal organs and extremities will be in place.

To get there, your baby develops the following things this month:

  • Limbs and extremities
  • Fingernails
  • Toenails
  • External ears
  • Teeth
  • Reproductive organs
  • Intestines

And though your baby is too small for you to feel moving around, they're learning how to move their arms and legs.

Baby’s Size

Despite their developmental progress, your baby is still tiny. However, they continue to grow each day. While most babies start month three at about ½ an inch long, they end it at nearly 2 inches.

They also begin putting on a bit of weight. By the end of the month, your growing baby should be about ½ an ounce.

3 Months Pregnant: Your Body And Mind

Your baby isn’t the only one experiencing changes. Pregnancy impacts every aspect of your body, from your skin to your mind. Here’s what to expect:

Physical Changes

While you might not look pregnant, your body is hard at work growing another human. This takes a toll on you physically, and you’re likely experiencing some of the following symptoms.

Your Skin

Without hormones like progesterone and estrogen, you can't grow a baby. Unfortunately, these hormones can also wreak havoc on your skin.

Some women notice their skin becoming more sensitive or dry. Others get acne outbreaks.

In addition, the skin on your abdomen starts stretching since your uterus is expanding. While you may not have stretch marks yet, they're likely coming soon. The Mustela Stretch Marks Set can help keep your skin hydrated during this time.

Our Stretch Marks Oil and Stretch Marks Cream Fragrance-Free are made from naturally derived ingredients, so you don’t have to worry about using them throughout your pregnancy.

Your Baby Bump

Most women start to show during their third month of pregnancy. However, you likely won’t need maternity clothes just yet.

As your uterus grows, it will push against the ligaments in your abdomen. This sensation can cause discomfort or aching across your lower belly.

If you feel a lot of pain, you'll want to discuss it with your doctor. But since your uterus is pushing your other organs and rearranging your insides, some general discomfort is to be expected.

Morning Sickness

At month three, morning sickness is a spectrum. Some women experience it all day long, while others don’t feel sick at all. No matter how you’re feeling, there is some good news. By the end of the third month, most women find that their morning sickness starts to subside.

If you're still nauseous, try to stop thinking about it. Your mind and body are uniquely connected, so the more you expect to feel sick, the more likely you actually will be.

Instead, keep your mind busy thinking about other things. It might not take away nausea completely, but it can help.

A Bit Of Discharge

Pregnant women often experience a thin, milky white vaginal discharge throughout the first trimester. This is primarily due to increased estrogen.

This type of discharge is perfectly normal during pregnancy, and it helps keep the area clean to protect your baby from infection. However, contact your doctor immediately if you notice bright red blood or a foul-smelling discharge. Both of these could be signs of something more serious.

Emotional Changes

Along with the physical changes you're dealing with, you’ll also experience numerous emotional ones. Let's look at a few.

Lacking Energy

You are growing another person inside you. It's a 24/7 process that requires a lot of energy. No wonder you may feel run down right now!

Even if you don't feel like it, make sure to get plenty of rest each day. Give yourself permission to take frequent breaks to recharge.

Remember that the second trimester often brings a fresh burst of energy. Until that happens, it’s OK to take it slow.

Feeling Worried

Even if you've never been particularly anxious, it's normal to feel worried and stressed during pregnancy. You may be having a hard time adjusting to the idea of being a parent, or you could just be overwhelmed by all the changes happening in your life right now.

It's helpful to talk to someone about these worries. Consider confiding in family members or friends who have been through this experience.

You could also join online forums and connect with other moms-to-be who may better understand what you're going through.

Having Mood Swings

Happy, sad, angry,'s all part of being pregnant. Mood swings often come with the territory, so don't be too hard on yourself if you struggle to stay calm and collected.

It can help to practice mindfulness techniques, such as deep breathing and visualization. These can help keep your emotions in check and prevent them from spiraling out of control.

3 Months Pregnant: Doctor Visits

At this point in your pregnancy, you should be visiting your doctor or midwife about once a month. During these visits, they will check on the well-being of both you and your baby.

Check Baby’s Heartbeat

Typically, you'll be able to hear your baby's heartbeat with a doppler after week 10. It's always a magical experience to listen to the horse galloping sound for the first time.

First Trimester Screening

At this stage of pregnancy, you may be offered a first-trimester screening test to check for abnormal results from blood tests or ultrasounds.

This screening can provide helpful insight into any potential health issues that could arise. However, some of them have serious risks. Always talk to your doctor and ask questions. And remember, you have the right to opt out of any testing.

Chorionic Villus Sampling (CVS)

This test involves taking a sample of placental tissue and analyzing it for any chromosomal abnormalities or other problems. It's typically done between weeks 10-12 of pregnancy.

Cell-Free DNA Testing Or Non-Invasive Prenatal Screening (NIPS)

For this type of test, your doctor will collect a blood sample from you and check it for genetic anomalies. It's a non-invasive way to check on the health of your baby.

Possible Ultrasound

If you didn't have a previous early pregnancy ultrasound, your doctor may suggest one to examine your baby's physical growth. This can provide reassurance that everything is going well.
