Our interactive gestational calculator helps you determine which week of pregnancy you are in today. Understanding your weekly progress is key to tracking fetal development and preparing for your child's birth.
While calendar months vary, pregnancy is often described as lasting 10 lunar months (each exactly 4 weeks long). For instance, weeks 1 to 4 make up month 1, weeks 5 to 8 make up month 2, and weeks 37 to 40 complete month 10. This explains why a 40-week pregnancy equals roughly 9 calendar months.
Tracking your pregnancy by weeks instead of months is a clinical standard. Fetal development moves rapidly in short periods. A difference of a single week determines whether a specific screening scan can be performed or whether certain medications can be safely prescribed.

Medical answers to standard queries regarding pregnancy calculations, due dates, and trimester guidelines.
You can calculate your pregnancy weeks by counting the number of days elapsed since the first day of your Last Menstrual Period (LMP) and dividing by 7. The quotient is your current week of pregnancy.
Yes, early detection pregnancy tests can show a positive result as early as 3 weeks and 4 days of gestational age, which is roughly 9 to 12 days after conception.
During the 4th week, the blastocyst implants into the uterine wall. The placenta and amniotic sac start forming, and early pregnancy hormones (hCG) begin to rise, making home pregnancy tests positive.
If you conceived exactly 4 weeks ago, you are clinically considered 6 weeks pregnant. This is because gestational age is measured from the first day of your last period, which is typically 2 weeks before conception.
Pregnancy is divided into three key blocks: First Trimester (weeks 1 to 13), Second Trimester (weeks 14 to 27), and Third Trimester (weeks 28 to 40+).
Because the exact day of ovulation and conception is hard to determine without laboratory monitoring, clinical guidelines standardize all pregnancy calculations starting from the last period (LMP), which is a clear and memorable date.
A 40-week pregnancy equals exactly 10 lunar months (each containing 4 weeks), which is roughly equivalent to 9 calendar months and 7 days. This explains the discrepancy when talking about weeks versus months.
If you have a longer menstrual cycle (e.g., 34 days), your ovulation happened later than the standard day 14. Our calculator adjusts for this delay, subtracting the offset from your gestational weeks to ensure accurate timing.
A baby's heart begins to beat around week 5 or 6 of pregnancy. It is usually clearly visible on a transvaginal ultrasound scan by week 6 or 7.
Once you enter your due date or LMP in this calculator, you can download the Gynosakhi app. Enter your timeline in your profile, and the app will unlock weekly guides, symptom trackers, and 3D fetal models.
