Pregnancy Week by Week/Week 4: Implantation

Week 4: Implantation
Week 4 of pregnancy is a critical period when the blastocyst implants itself into the uterine lining, initiating the foundation for your baby's development. This week marks the beginning of the formation of three distinct cell layers that will eventually develop into various body systems. The placenta also starts to form and will nourish your baby throughout pregnancy. At this stage, your baby is about the size of a poppy seed, a tiny but significant milestone in the journey of life.
Your Body During Week 4
As your body adjusts to these changes, you may notice that your period is missed and pregnancy hormones begin to rise, leading to early pregnancy symptoms such as fatigue, breast tenderness, and nausea. Home pregnancy tests may now show positive results, confirming your pregnancy.
Hati Health Tips for Week 4
It is essential to schedule your first prenatal appointment during this time to ensure both your health and your baby's development are closely monitored. To support a healthy pregnancy, begin avoiding foods that are unsafe during pregnancy and start tracking your symptoms to monitor your well-being throughout this journey.
Taking these steps early on can help you maintain a healthy pregnancy and prepare for the exciting months ahead.

Non-invasive Prenatal Test - Basic (NIPT - Basic)
The Non-Invasive Prenatal Test (NIPT – Basic) uses a simple blood sample from the mother to screen for common chromosomal conditions, including Trisomy 21 (Down syndrome), Trisomy 18, Trisomy 13, and sex chromosome aneuploidies like Turner and Klinefelter syndromes. It also includes fetal gender determination and may report incidental chromosomal findings.
Safe, highly accurate, and available as early as 10 weeks into pregnancy, NIPT – Basic empowers expectant parents with early, reliable insights.

Non-invasive Prenatal Test - Pro (NIPT - Pro)
NIPT – Pro is a safe, non-invasive blood test available from 10 weeks of pregnancy. It screens for Trisomy 21, 18, 13, sex chromosome aneuploidies, and 92 microdeletions and duplications. It also includes fetal gender and incidental findings, giving parents a detailed view of their baby’s genetic health.

OBGYN
Take charge of your reproductive health with an OB-GYN consult—your first step to expert care for pregnancy, periods, PCOS, menopause, and more.

Pregnancy Test (Serum)
Our Pregnancy Serum Test provides accurate, early detection of pregnancy by measuring hCG levels in the blood. Performed through a simple blood draw, this lab-based test offers greater sensitivity than urine tests and is ideal for confirming pregnancy soon after a missed period. Recommended for patients with early symptoms or those seeking reliable confirmation, it supports timely care and informed next steps.

Pregnancy Test (Urine)
A urine pregnancy test detects the hormone hCG, which is produced shortly after a fertilized egg implants in the uterus. Using a urine sample, the test identifies hCG through a simple device—typically showing a line or symbol for a positive result. A negative result suggests no hCG is detected, though early testing or improper use may affect accuracy.

Prenatal Screening
Start your pregnancy with confidence through our comprehensive First Trimester Screening Package. This early checkup includes essential tests to assess your health and your baby’s development, such as OGTT (gestational diabetes screening), Pap smear, Complete blood count (CBC), Hepatitis B screening, Urinalysis, and Transvaginal and whole abdomen ultrasounds.
It is ideal for expectant mothers in their first trimester—whether newly confirmed, planning a prenatal visit, or seeking early detection of potential risks.
