What Happens to Your Body During the First Trimester?

The first trimester is the first 12 weeks of pregnancy. Along with the emotional changes you are experiencing, your body begins going through some remarkable changes almost immediately. Even though your baby is still very small, your body is already working hard to support your growing baby.

Here's what you may experience during these early weeks.

1. You May Feel Extremely Tired

One of the earliest pregnancy symptoms is fatigue. You may find yourself feeling exhausted even after getting a full night's sleep.

Your body is producing more hormones, your blood volume is beginning to increase, and your body is using extra energy to support the developing pregnancy.

Don't be surprised if you need more rest than usual. When possible, listen to your body and give yourself permission to slow down.

2. Your Breasts May Become Tender

Hormonal changes can cause your breasts to feel sore, swollen, or more sensitive than usual. Your nipples may also become more sensitive, and you may notice changes in the appearance of your breasts. These changes can begin surprisingly early in pregnancy.

3. Morning Sickness May Begin

Despite its name, "morning sickness" can happen at any time of day. Some women experience occasional nausea, while others experience significant vomiting. Certain smells, foods, or even an empty stomach can make nausea worse.

For many women, morning sickness begins around the sixth week of pregnancy and improves as the first trimester comes to an end. Keep in mind, everyone's body is different.

Small, frequent meals and staying hydrated may help. If you are unable to keep fluids down or are concerned about severe vomiting, talk with your healthcare provider.

4. You May Need to Use the Bathroom More Often

Frequent urination is another common early pregnancy symptom. Hormonal changes and increased blood flow to your kidneys can cause you to urinate more frequently. As pregnancy progresses, your growing uterus can also put additional pressure on your bladder.

5. Your Emotions May Feel Different

Pregnancy isn't just a physical experience. Hormonal changes can affect your emotions as well. You may feel happy one moment and overwhelmed the next. You might experience increased anxiety, irritability, or unexpected tears.

If you're facing an unexpected pregnancy, these emotions may be even more complicated. You don't have to feel a certain way just because you're pregnant. Give yourself time to process what you're experiencing and consider talking with someone you trust.

6. You May Experience Food Cravings or Aversions

Foods you once loved may suddenly sound terrible. You may also develop strong cravings for particular foods. Sometimes even the smell of a familiar food can suddenly make you nauseated. These changes are common during pregnancy and are largely related to hormonal changes.

7. You May Notice Bloating and Constipation

Hormonal changes can slow down your digestive system, which may lead to bloating, gas, or constipation.

Drinking plenty of water, eating fiber-rich foods, and staying physically active when your healthcare provider says it's appropriate can help support healthy digestion.

8. You May Have Mild Cramping

Some women experience mild cramping during early pregnancy. As your body adjusts to pregnancy, you may experience sensations similar to menstrual cramps. Mild cramping can be normal, but severe or persistent pain should not be ignored.

If you experience significant pain, especially if it is accompanied by bleeding, contact your healthcare provider immediately.

9. Your Body Is Already Supporting Your Baby's Development

Even though your baby is only a tiny fraction of the size they will eventually become, an incredible amount of development is taking place during the first trimester.

The baby's major organs and body systems begin developing during these first weeks. The heart begins beating early in pregnancy, and the brain, spinal cord, limbs, and other structures begin taking shape.

Your body is providing the environment and nutrients your baby needs during this extraordinary period of development.

When Should You Call Your Healthcare Provider?

Many first-trimester symptoms are completely normal, but some symptoms should receive prompt medical attention.

Contact your healthcare provider if you experience things such as:

• Heavy vaginal bleeding

• Severe or persistent abdominal or pelvic pain

• Severe vomiting or inability to keep fluids down

• Fainting or significant dizziness

• Fever or other concerning symptoms

When you're unsure whether something is normal, it's always appropriate to contact your healthcare provider and ask.

Give Yourself Grace During the First Trimester

The first trimester can be exciting, uncomfortable, confusing, and overwhelming all at the same time. Your body is doing something remarkable, even on the days when you don't feel your best. Give yourself permission to rest, ask questions, accept help, and take care of yourself.
