First Trimester Essentials: Why You Should Invest in Prenatal Checkups So Early
May 19, 2025 • 7 MIN READ
Nagsimula pa lang ang journey namin as first-time parents, pero alam na naming mahalaga ang bawat hakbang—lalo na sa unang trimester ng pagbubuntis.
At just one month pregnant, your body is already working overtime—even if you don’t see it yet. Your baby is rapidly developing inside your womb, forming vital organs like the brain, spinal cord, and heart. But while your baby is growing, this early stage is also the best time to invest in your health through proper prenatal checkups.
What’s Happening in Your First Trimester?

The first trimester covers weeks 1 to 12 of your pregnancy. Even before you notice a baby bump, hormones are shifting inside your body to support new life. That’s why many women start feeling:
- Pagkapagod o sobrang antok
- Nausea and vomiting (a.k.a. morning sickness)
- Tender or swollen breasts
- Mood swings
- Cravings o minsan, food aversions
These changes are completely normal, but they can also be confusing and even overwhelming—lalo na sa mga unang beses pa lang magbubuntis. That’s why we decided to go for a complete set of prenatal screenings early on.
What Can You Expect at the Doctor?

When you first learn you're pregnant, the next step is to book that all-important appointment with your OB-GYN. The doctor will become your main guide in caring for you and your baby. If you're not already on prenatal vitamins, it’s time to start them—immediately! Ideally, women should take folic acid for at least a year before conception, but starting now is key for your baby’s development.
During your first visit, your doctor will take a full health history and perform a physical and pelvic exam. Expect a thorough checkup, and your doctor may also:
- Perform an ultrasound to confirm the pregnancy
- Take your blood pressure
- Test for sexually transmitted infections (STIs), HIV, and hepatitis
- Estimate your delivery date (typically around 266 days from the first day of your last period)
- Screen for risk factors like anemia and check thyroid levels
- Check your weight
It’s a lot to process, but these early screenings are essential for a healthy pregnancy journey!
Our First Trimester Checkups: A Breakdown
Here’s a closer look at the tests we chose, and why they matter so much—especially if you're in your first trimester like us.
✅ OGTT Pregnant (75 gms)
This test checks how your body handles glucose. It’s a way to screen for gestational diabetes, which can develop during pregnancy and affect your baby’s health if left untreated.
✅ Pap Smear – Conventional
Yes, even while pregnant, your OB might recommend a Pap smear—especially if it’s been a while since your last one. This test screens for cervical cancer and ensures your reproductive system is healthy.
✅ Complete Blood Count with Platelet Count
This test checks for anemia and other blood disorders. Your body is producing more blood during pregnancy, and it’s crucial to monitor if you’re getting enough iron and nutrients.

Complete Blood Count with Platelet Count
Starts at ₱ 250
✅ HBsAg (RAPID) Screening
This is a hepatitis B screening. If you test positive, your baby may need additional protection at birth. Early detection = early protection.
✅ Urinalysis (Macroscopic and Chemical Examination)
This checks for urinary tract infections (UTIs) and signs of preeclampsia (like protein in the urine). UTIs can be dangerous during pregnancy if not treated early.
✅ Ultrasound (Transvaginal)
This early scan confirms the baby’s location in the uterus and checks for a heartbeat. It’s one of the first magical moments—you’ll hear your little one's heartbeat for the first time. 💓
✅ Whole Abdomen Ultrasound – Appointment Only
Though not always needed this early, this ultrasound provides a broader view of your abdominal organs. It’s best scheduled if your OB recommends checking specific conditions.
Symptoms at 1 Month Pregnant

At this early stage, you’re not likely to notice many symptoms. After all, you just found out you’re pregnant! But some things to keep an eye out for include:
- Fatigue: Your body is working overtime to support your growing baby, which means plenty of rest is essential.
- Sore boobs: Hormonal changes may make your breasts feel extra tender.
- Cramping and belly pains: Mild cramps and stomach discomfort are common and can be caused by uterine changes or bloating.
- Peeing all the time: Your kidneys ramp up waste production during pregnancy, so bathroom trips increase.
- Spotting: Light pink or brown spotting is normal, but if it’s bright red or heavy, contact your doctor.
Fetal Development at 1 Month Pregnant

Your baby is working hard on developing from a fertilized egg full of multiplying cells into what we call an embryo. They’re already starting to build vital organ systems, and the placenta and umbilical cord are beginning to form. Right now, your baby is about 6 or 7 millimeters in size and growing rapidly.
Figuring Out Your Due Date

Your doctor will typically calculate your due date using the first day of your last period, adding 40 weeks from that date. This is an estimate, and factors like cycle length can affect accuracy. If you know the exact date of conception, discuss it with your doctor to adjust the due date.
Checklist for Your Pregnancy

Here’s a quick checklist for your first month of pregnancy:
- Schedule your first appointment with a midwife or OB-GYN.
- Start taking a prenatal vitamin with at least 400 micrograms of folic acid.
- Consider making a plan for a healthy diet and light exercise.
- Kick harmful habits like smoking, drinking, and drug use to the curb.
- Get plenty of rest and take care of yourself!
When to See a Doctor

At 1 month pregnant, it’s common to feel a bit of excitement, nervousness, and extreme fatigue. However, if you experience any of the following, don’t hesitate to contact your doctor immediately:
- Severe abdominal pain or cramping
- Bright red vaginal bleeding or heavy bleeding
- Fever or chills
- Severe dizziness or headaches
- Severe nausea or vomiting that won’t stop
