Understanding Pregnancy: What Happens in the First Trimester?
The initial trimester of pregnancy, which is from conception until the end of week 13, is a time of astonishing change for the expecting parent and the developing fetus. Knowing what key changes occur can help prepare for what is to come.
Fetal Development
Weeks 1-4: The zygote is fertilized and begins dividing rapidly. It then implants into the uterine lining. By the end of week four, the embryo is approximately 1/6-inch long and has differentiated into a head and trunk, while limb buds, which will eventually develop arms and legs, have begun to form.
Weeks 5-8: the major organ systems of the body begin to develop. By the eighth week of pregnancy, the embryo has transitioned to a fetus that measures approximately 1/2 inch (11 to 14 millimeters) from head to tailbone. The upper lip and nose as well as other facial features start to develop and the trunk and neck begin to straighten.
Weeks 9-13: The external genital organs develop and fingernails and toenails appear. Eyelids develop and fetal movements increase. The arms and legs are fully formed at this time. By the end of week 12, all organs have developed as well as bone and muscle development and the fetus is practicing swallowing.
Maternal Changes and Symptoms
During the first trimester, individuals will experience an array of symptoms due to the emergence of hormones:
Nausea and Vomiting: Better known as morning sickness, these symptoms can occur at any time of the day.
Breast Tenderness: Body-influenced hormonal fluctuations can cause breasts to be sensitive or sore.
Fatigue: Increased levels of the hormone progesterone contribute to higher levels of tiredness.
Frequent Urination: As the uterus grows, it presses on the bladder, leading to increased bathroom trips.
Mood Swings: Fluctuations in emotion are common from changes the hormones induce.
All of these symptoms will vary in range and intensity, and some individuals will not experience them at all.
Prenatal Care and Lifestyle Factors
Starting prenatal care is essential for monitoring the health of the parent and baby. It is ideal to see a healthcare provider once pregnancy is confirmed, so screenings and the plan of care can begin. The following are important lifestyle factors in the first trimester:
Nutrition: Eating a varied and balanced diet that is high in folic acid, iron, calcium, and other nutrients is important for fetal development.
Hydration: Drinking plenty of fluids can help the overall health of the parent and can help with some symptoms of pregnancy.
Limit Harmful Substances: It is suggested to avoid drinking alcohol and/or smoking. Additionally, medications should be avoided if they are not prescribed by a qualified healthcare provider.
Rest: Prioritizing rest and deciding to reduce stress can enhance health during pregnancy.
Taking the first steps of pregnancy is both a thrilling and a daunting task. Educating yourself about first-trimester developments and changes can make the experience for parents more confident and less stressful.

Folic Acid for Pregnancy: Importance, Sources, and Recommended Intake
Folic acid is a necessary nutrient with a critical role in pregnancy and the development of the fetus. It is a synthetic form of folate (Vitamin B9) and is important for DNA synthesis and cell growth, as well as helping to prevent neural tube defects (NTDs) in developing babies. The early stages of pregnancy (first eight weeks) are essential for organ formation, and getting enough folic acid will help ensure the baby’s brain, spine, and overall nervous systems are developing properly.
Why Is Folic Acid Important?
Folic acid is vital in early pregnancy, in particular the first few weeks, when the neural tube is forming that will develop into the brain and spinal cord. When folic acid is not consumed at increased levels during this crucial beginning phase in pregnancy, there is a higher risk of birth defects like spina bifida or anencephaly.
Spina Bifida: The embryonic neural tube does not completely close over the spinal cord and can result in lifelong disability, mobility concerns, and neurologic consequences.
Anencephaly: The openings in the skull and brain do not properly develop and mostly often leads to stillbirth or infant death.
Congenital Heart Defects: Some research indicates that folic acid may also help decrease the chances of congenital heart defects in newborns.
Cleft Lip and Palate: Growing evidence supports that folic acid intake might also help decrease the chances of these craniofacial syndromes, which affect both feeding and development of speech in babies.
Adequate consumption of folic acid may reduce the chances of these conditions by as much as 70%, making supplementation vital to prenatal care.
Recommended Amounts of Daily Folic Acid
Health organizations recommend the following intake of folic acid:
Before Conception: 400 micrograms (mcg) daily since neural tubes close within the first 28 days of pregnancy, often before a woman even knows she is pregnant.
During Pregnancy: 600 mcg daily because of rapid fetal growth, increasing maternal blood volume as pregnancy progresses and placental development.
During Breastfeeding: 500 mcg daily because of milk production and the baby’s continued neurological development.
For women at high risk of having a newborn with NTDs, such as those with a history of NTDs in previous pregnancies or with certain medical conditions such as diabetes or epilepsy, doctors may prescribe as much as 4,000 mcg daily, under medical supervision.
Sources of Folic Acid and Folate
While folic acid can be found in fortified foods and supplements, folate occurs naturally in a variety of foods. Diets that incorporate both natural dietary folate sources and folic acid supplements provide the best chance for adequate intake.
Folic Acid (Fortified Sources & Supplements)
Fortified cereals and breads
Folic acid-enriched pasta and rice
Certain breakfast cereals and energy bars
Prenatal vitamins and folic acid tablets
Folate (Natural Sources)
Leafy green vegetables (spinach, kale, romaine lettuce)
Citrus fruits (oranges, grapefruits, lemons)
Legumes (lentils, chickpeas, black beans, peas)
Nuts and seeds (sunflower seeds, peanuts, almonds)Eggs, and organ meats such as liverIt is worth noting that the body uses synthetic folic acid more effectively than natural folate- so taking a prenatal vitamin is a good way to ensure the daily recommendation is met.
Folic Acid and the MTHFR Gene Mutation
One of the main things that come up for discussion is if people with MTHFR gene variants will effectively process FOLIC acid. The MTHFR gene codes for an enzyme that assists in converting FOLIC acid to methylfolate, the usable form of folate. Some people with MTHFR gene mutations may have lower enzyme activity, which raises concerns about FOLIC acid consumption. Evidence shows that MTHFR gene variants don’t negate the benefits of folic acid supplements. Some women may elect to take methylated folate or the active form of folate to assist with absorption. Seeking medical advice, along with genetic testing if necessary, will help find the right support that takes your circumstances into consideration.
Best Practices for Taking Folic Acid
Start early: ideally, folic acid supplementation should begin one month prior to conception to ensure levels are sufficient during early fetal development.
Eat a balanced diet: Eating a wide variety of folate-rich foods and taking supplements enhances nutrition.
Check prenatal vitamins: Most prenatal vitamins include Folic acid, but it can be reassuring to check the quantity for additional peace of mind.
Be aware of side effects: Generally Folic acid is safe to take, however, ingesting high amounts (greater than 1,000 mcg daily without the consultation of your medical provider) over a prolonged time may mask a vitamin B12 deficiency or create another type of imbalance.
Speak to a healthcare provider: This may be more important if you are at a higher risk for a NTD, you have a genetic risk or limited access to dietary sources.
Summary
Folic acid is a key nutrient in supporting a healthy pregnancy, substantially reducing the risk of neural tube defects and aiding in fetal development. To support maternal health during pregnancy, moms-to-be should incorporate food sources of folate and use folic acid supplements in daily dietary intake. Starting these supplements early on (ideally before conception and throughout pregnancy) while maintaining a well-balanced diet on folate-rich foods and utilizing professional resources will result in the best outcomes for mother and baby.
