Pregnancy Week 8: Embryo Growth and Risk Reduction

World
Motherhood

At 8 weeks pregnant, you are in the final stretch of the second month of gestation. Although your belly may not be showing yet, major changes are happening inside you.
It is a good time to continue with a healthy diet, take prenatal vitamins, and attend medical checkups to ensure everything is progressing correctly.
Every day is another step in this incredible adventure. Your baby continues to grow, and your body is adapting to give it the best!

Symptoms

Nausea and vomiting: The hCG hormone continues to rise, which can intensify nausea.
Extreme fatigue: The body works hard to nourish the baby, causing significant energy depletion.
Sensitive and larger breasts: They are preparing for lactation and may feel heavier or more tender.
Increased need to urinate: The uterus continues to grow and puts pressure on the bladder.
Mood swings: Hormones can provoke intense emotions, from happiness to irritability or tearfulness.
Food cravings or aversions: Some foods may become irresistible, while others may cause rejection.
Constipation and gas: Progesterone slows down digestion, causing bloating and slower bowel movements.
Heartburn: This is common due to the relaxation of the esophageal sphincter caused by hormones.
Increased vaginal discharge: A whitish discharge (leukorrhea) is normal and helps prevent infections.

Embryo size

During week 8, the embryo measures approximately 1.6 cm to 2 cm, similar to the size of a raspberry or a bean. Its weight is around 1 gram.
Development this week:
The embryo now has a more defined shape, with a growing head, trunk, and limbs.
Fingers and toes begin to separate, although they are still joined by a membrane.
The heart beats rapidly (between 140-180 beats per minute).
The brain continues to develop, with the formation of more neural connections.
The eyes are more defined, although still covered by skin.
The nose and ears take more shape, although they are not fully developed.
Fun fact: Although it cannot be felt yet, the baby is already starting to move inside the uterus.

Doing high-impact exercises
Avoid activities like running intensely, jumping, or lifting heavy weights, as they can affect the pelvic floor and increase the risk of injury.
Eating raw or undercooked foods
Avoid sushi, raw seafood, undercooked meats, and raw eggs, as they may contain dangerous bacteria such as listeria and salmonella.
Exposing yourself to high temperatures
Saunas, hot tubs, and very hot baths can raise your body temperature and affect the baby’s development.
Self-medicating
Some medications can be dangerous during pregnancy. Always consult your doctor before taking any drug or supplement.
Handling toxic chemicals
Avoid contact with strong cleaning products, pesticides, and hair dyes containing ammonia.

Getting overly stressed
Stress can affect your health and the baby’s. Try to relax with techniques like meditation or prenatal yoga.
Doing restrictive diets
Your body needs essential nutrients for the baby’s development. Do not follow extreme diets or eliminate food groups without consulting a specialist.
Making sudden or risky movements
Avoid carrying heavy objects, bending over abruptly, or standing for long periods without rest.

Frequently Asked Questions

Why do I have a metallic taste in my mouth?

This is due to hormonal changes, especially the increase in estrogen. It is called dysgeusia and is common in the first trimester. Chewing sugar-free gum or rinsing with water and lemon may help.

Can I still have sex?

Yes, in most cases it is safe and beneficial. However, if you have bleeding, a history of miscarriage, or risk of premature labor, consult your doctor.

Is it normal for my gums to bleed when brushing?

Yes, hormonal changes can make the gums more sensitive and inflamed (pregnancy gingivitis). Use a soft-bristled brush and visit the dentist if bleeding is frequent.

Can I still use my usual perfume?

If strong smells make you nauseous, try switching to milder fragrances or temporarily avoiding them.

Is it normal to have headaches at this stage?

Yes, it can be due to hormonal changes, lack of sleep, or dehydration. Resting, drinking enough water, and avoiding stress may help.

How common is constipation this week?

It is quite common due to the increase in progesterone, which relaxes the intestinal muscles. Consuming fiber, drinking water, and doing light exercise may help.

How do I know if my baby is okay if I can’t feel movement yet?

It is normal not to feel movements at this stage, as the baby is still very small. Ultrasounds and medical checkups confirm its development.

Can I get gel or acrylic nails done?

Yes, but make sure to do it in a well-ventilated place and avoid products with strong chemicals like formaldehyde.

Why do I have more gas and a bloated feeling?

Pregnancy hormones slow digestion, which can cause gas. Eating slowly and avoiding foods that cause bloating may help.

Is it safe to drink herbal teas or infusions?

Some teas can be harmful during pregnancy. Avoid rue, boldo, anise, and licorice tea. Consult your doctor before consuming any infusion.
