Month 4

Weeks 14-17: Embracing the Changes of the Second Trimester

How Big is Baby?

Between 14-17 weeks, your baby grows from the size of a lime to an apple. Key developments include well-defined hair, eyelids, and nails, with the heartbeat audible via Doppler. The reproductive organs become visible, and the nervous system matures, allowing thumb sucking and facial expressions. By week 15, organs settle in place, and purposeful movements, like smiling, begin. By week 16, lips form, and the baby can hear and respond to light, although its eyes remain closed.

Discovering More Changes

As you progress into the fifth month, the initial symptoms of pregnancy, like nausea and fatigue, are likely behind you. This period is often marked by a noticeable baby bump and increased energy levels, allowing you to enjoy this phase of your pregnancy. However, you may also experience new symptoms such as round ligament pain and slight swelling.

You may also find yourself needing to urinate more frequently. This is because your growing baby is putting pressure on your bladder, reducing its capacity. Staying hydrated is crucial, even if it means more trips to the bathroom.

Another common change during this time is the appearance of stretch marks. As your baby continues to grow, your skin stretches to accommodate the new life within you. Applying lotion regularly can help maintain your skin’s elasticity and potentially reduce the severity of stretch marks. Look for lotions that contain ingredients like cocoa butter, shea butter, or vitamin E, which are known to help moisturize and nourish the skin.

Scheduling Your Next Doctor Appointment

Regular check-ups continue to be crucial. Your monthly prenatal appointments will monitor your baby’s development and your health. Expect to have more frequent visits starting in week 28, moving from monthly to biweekly.

What to Expect at Your Doctor Appointment at 14-17 Weeks:

Every prenatal visit:

  • Physical Exam: This may include checking your weight, blood pressure, and the circumference of your belly.
  • Urine Sample: to check for protein and glucose

14-17 week-specific:

  • Prenatal Screening Options*: The Quad screen is a series of bloodwork that can be done starting at 14 weeks and tests for chromosomal conditions or neural tube defects. Amniocentesis is an invasive procedure that can be tested at week 16 for hundreds of genetic and chromosome-related conditions.

*See What to expect at your Dr. appointments: Typical tests and timeline for an in depth look at what these tests mean and why you’ll be tested for them.

To make the most of your prenatal visit:

  • Update Your Medical History: Note any new symptoms or concerns since your last visit.
  • Prepare Questions: Write down any questions you have about your pregnancy, your baby’s development, or what to expect next.
  • Bring a Support Person: If possible, bring someone with you for support and to help remember the information discussed.

Fun Fact: Why Do We Measure This Month as Weeks 14-17 Instead of 14-18?

You might wonder why the fourth month of pregnancy is often referred to as weeks 14-17 rather than weeks 14-18. Here’s the reason: pregnancy is generally calculated as a 40-week period, starting from the first day of your last menstrual period. These two weeks, known as the gestational age, include the period of time before conception actually occurs.

Understanding the Measurement

  • Pregnancy is traditionally divided into trimesters, each spanning roughly three months. However, each month in a trimester isn’t always exactly four weeks (28 days) because calendar months vary in length (30 or 31 days).
  • Using a lunar calendar, which counts four weeks per month, would mean each trimester should be exactly 12 weeks. But because actual calendar months vary, the extra days accumulate.

This slight adjustment ensures that each trimester aligns more accurately with the natural calendar and the developmental stages of the baby, providing a more precise framework for monitoring and managing the pregnancy.

Sharing the News

By the second trimester, many parents-to-be feel more comfortable sharing their pregnancy news with a wider circle. The risk of miscarriage has significantly decreased, and your growing baby bump might make it harder to keep the news a secret. Whether you decide to share the news now or wait, the choice is entirely yours. Some people opt for a gender reveal to share the news and the baby’s gender at the same time. Be sure to let your doctor know whether you want to know the gender, so they don’t accidentally spill the beans! If you plan on celebrating the gender and haven’t done so yet, be sure to check out our page ‘Preparing for a Gender Reveal’ to help you plan and be informed on what to look forward to.

Here’s an ideal timeline of when you should start planning for your upcoming baby-related agenda:

  • Baby Registry: The sooner the better. Add necessities in the 1st trimester, add specifics once you find out the gender. Aim to finish before the baby shower (usually month 7 or 8).
  • Gender Reveal: Start planning around 10 weeks if you plan on getting the NIPT bloodwork, or 16 weeks – 1 month before the anatomy scan.
  • Nursery: Anytime after the 1st trimester is ideal. This includes adding furniture to the registry, and clearing space for the baby.
  • Baby Shower: If a venue is on the table, start planning right after your gender reveal so you have time to book. If that isn’t an issue, start planning in month 5 or 6 to give yourself a good month or two to get everything in order.
  • Birth Plan: Ideally, start thinking about this as soon as you find out your pregnant. Finalize your wants and needs with your OB by 36 weeks.
  • Hospital Bag: You’ll want to have this packed and ready to go by week 38 just in case.

Emotions in the Fourth Month

By the fourth month, many people start to feel on top of the world. The second trimester often brings relief as nausea and sciatica subside, replaced by increased energy. This surge in vitality allows expectant parents to take full advantage of their nesting instincts before the inevitable exhaustion of the third trimester sets in.

If you don’t feel so great just yet, that’s okay too. Your pregnancy journey is unique, and not feeling fantastic doesn’t make your experience any less valid or beautiful. Remember, you’re growing a human!

With the big news out in the open, many parents-to-be feel more excited and enjoy sharing their journey with friends and coworkers. On the other hand, some may prefer to keep a lower profile to maintain a calm environment. As your baby bump starts to show—especially during the summer months when layering isn’t an option—be prepared for people to want to touch your belly.

It’s entirely your choice whether to let people touch you. If you’re uncomfortable, here are some polite ways to decline:

  • Be Direct but Kind: “I’d prefer if people didn’t touch my belly.”
  • Use Humor: “The baby isn’t taking visitors right now.”
  • Redirect: “I’m not comfortable with belly touches, but I’d love to talk about the pregnancy!”

Planning for a gender reveal or baby shower may be top of mind. Traditionally, these celebrations were hosted by others to reduce stress for the expectant parents. However, more parents are now hosting their own parties. If you’re planning your own, be mindful not to overextend yourself. Stay hydrated, eat regularly, and don’t hesitate to ask for help.

Diet and cravings can also be a source of guilt during pregnancy. While all sources recommend a healthy, balanced diet, sometimes baby wants what baby wants. As long as your provider isn’t concerned, try to relax. Even after indulging in that fifth taco from Taco Bell, rest assured your baby is growing happy, healthy, and safely in utero. If you feel anxious about your diet, discuss it with your healthcare provider to gain peace of mind.

Embrace this special time, celebrate your milestones, and take care of yourself. Your journey is unique and beautiful, and you’re doing an amazing job!

Taking the Next Steps

As you progress through the fourth month, there are several important steps to continue or start:

  • Continue Prenatal Vitamins: Keep taking your prenatal vitamins daily to support your baby’s development.
  • Educate Yourself: Continue learning about pregnancy and what to expect in the coming months.
  • Hydrate and Eat Well: Maintain a balanced diet and stay hydrated.
  • Avoid Harmful Substances: Continue to avoid alcohol, tobacco, and any other harmful substances, like cat litter.
  • Applying Lotion: It’s a good time to start applying lotion to your skin if you haven’t already, especially your belly. As your baby continues to grow, it may grow faster than the elasticity in your skin is prepared for, resulting in stretch marks. Applying lotion now is a great preventative for deep, dark spots. Of course, stretch marks and their severity are also partly genetic, so don’t be too hard on yourself if you find yourself lathering up daily only to continue to see new stretch marks forming. The body is doing remarkable things at a very fast pace!
