Week 8 at a glance

At 8 weeks, the embryo is often about 14–16 mm (0.55–0.63 in), roughly the size of a raspberry. Early spontaneous movements may be happening, but they are too small to feel and are usually felt much later in pregnancy.

8 weeks pregnant is about 2 months. You are in month 2 of pregnancy and the first trimester.

Your baby at 8 weeks

Your Embryo Is About the Size of a Raspberry

Early movements at this stage are a sign of the developing nervous system. They are not purposeful kicks, and they are too small to feel.

How the embryo is growing

By week 8, the embryo is often 14–16 mm (0.55–0.63 in) long. Arms and legs are lengthening, elbows are beginning to form, and fingers are starting to separate from one another.

  • The face becomes more recognizable as the upper lip and nose develop.
  • The intestines temporarily extend into the base of the umbilical cord. This is a normal stage of development.
  • A heartbeat is often visible on ultrasound by this week.
Movements felt by the pregnant person usually begin in the second trimester, often between 16 and 25 weeks. Not feeling movement at 8 weeks is expected.

How you may feel

Hormones can intensify nausea, fatigue and emotional sensitivity. Eating small, frequent meals may help some people. Ask your provider about treatment options if vomiting is persistent.

Contact your provider right away, or seek urgent care, if you have uncontrolled vomiting, signs of dehydration, severe pain or bleeding.

Your body at 8 weeks

Why Pregnancy Fatigue Hits So Hard

Why are you so tired?

If you feel completely drained by the time you get home from work or sink onto the couch at 8 weeks of pregnancy, you are not alone. Extreme fatigue is one of the most common early pregnancy symptoms.

The role of progesterone

A main suspect is progesterone, a hormone that helps support the pregnancy. Its levels rise quickly in the first trimester. Some experts believe progesterone may have a calming effect on the nervous system, which could add to the sleepiness you feel. Other changes, such as higher blood volume and the hormone hCG, may also play a role.

How to manage fatigue

  • Listen to your body. Short naps of 20 to 30 minutes may help if you can fit them in.
  • Try to keep a regular sleep schedule, even on weekends.
  • Eat balanced meals with protein, fiber, and healthy fats. Steady blood sugar may help you feel less worn out.
  • Drink fluids throughout the day, and ask your provider how much water is right for you.
This tiredness is often temporary. For many people, energy improves by the start of the second trimester, around weeks 13 to 14.

When to talk to your provider

Fatigue is common, but ask your provider promptly if it comes with severe shortness of breath, dizziness, fainting, or extreme weakness or apathy. These symptoms can sometimes be caused by anemia or other conditions that need checking. Call 911 or go to the nearest emergency room if you have chest pain or trouble breathing.

Common symptoms at 8 weeks

Extreme tiredness

Feeling worn out, even after a full night of sleep, is very common this early. Short rests, an earlier bedtime, and lighter plans for the day can help you feel more steady.

Nausea

Some people feel queasy at any time of day, not just in the morning. Eating small, plain snacks often and keeping crackers by the bed may ease it for some people.

Breast tenderness

Breasts can feel sore, full, or heavy as hormone levels rise. A supportive, well-fitting bra, including a soft sleep bra, can make you more comfortable.

Needing to pee more often

Your kidneys work harder now, so you may get up to urinate more often, even at night. Drinking fluids steadily during the day, rather than all at once, can help with comfort.

Mood swings

Feeling teary, irritable, or emotional for no clear reason is common as hormones shift. Talking with someone you trust, or writing down your feelings, can help you process them.

Bloating or constipation

Hormones can slow digestion, which can cause gas, bloating, or constipation. Water, fiber from fruits, vegetables, and whole grains, and gentle daily movement such as a short walk may help.

Your week 8 checklist

Tests and appointments

  • First prenatal visit and routine bloodwork. Your first appointment often includes blood tests for blood type, anemia, immunity, and infections, along with a urine test and a review of your health history.
  • Due date confirmation ultrasound. Some providers offer an early ultrasound to confirm how far along you are and check the pregnancy's location and heartbeat.
For your partner: You can help by taking on more of the household tasks, such as cooking, cleaning, or errands, so your partner can rest. Offering to go with them to appointments and listening without rushing to fix things can also make a big difference.
