The moment that pregnancy test shows positive, the first question every Pakistani mother asks is “mera baby kab aayega?” A pregnancy calculator week by week answers exactly that. Whether you just found out or you’re already feeling those first flutters of movement, knowing your exact week helps you prepare for every milestone ahead.
A pregnancy calculator works by counting 280 days (40 weeks) from the first day of your last menstrual period (LMP). This is the same method your gynecologist uses during your first visit. While the exact delivery date can vary — only about 4% of babies arrive on their due date — this pregnancy due date calculator gives you a reliable timeline to plan appointments, tests, and your delivery preparation.
How Does a Pregnancy Week Calculator Work?
If you’re wondering “how many weeks pregnant am I?” — the calculation is simpler than you think. Take the first day of your last period and count forward. Every 7 days from that date equals one week of pregnancy. Most doctors in Pakistan use this LMP method as the standard pregnancy calculator by last period.
Here’s the basic formula: First day of last period + 280 days = Estimated Due Date (EDD). For example, if your last period started on January 1st, your estimated due date would be around October 8th. Your doctor may adjust this date slightly after your first ultrasound, especially if your cycle is longer or shorter than the typical 28 days.
Pregnancy Stages Week by Week: Trimester Breakdown
Understanding your pregnancy stages week by week helps you know what’s normal, when to expect changes, and what tests are coming. Here’s a complete trimester guide tailored for Pakistani mothers:
First Trimester (Weeks 1–12)
The first trimester is when the magic begins — and when morning sickness usually hits hardest. By week 5, your baby’s heart starts forming, and by week 8, all major organs are developing. This is the most critical period for the baby’s growth, which is why Pakistani doctors typically schedule the first ultrasound between weeks 6–8.
You may experience nausea, fatigue, sore breasts, and mood swings during these early weeks. Many Pakistani women keep their pregnancy private during this trimester, sharing the news only with close family — a cultural practice rooted in caution during these delicate early weeks. Your doctor will likely prescribe folic acid and iron supplements, and advise you to avoid heavy lifting and stressful situations.
Second Trimester (Weeks 13–27)
Often called the “honeymoon trimester,” this is when most mothers feel their best. Energy returns, nausea fades, and the baby bump starts showing get ready for everyone from your phuppo to your neighbour aunty to start giving advice! Around week 16–20, you’ll feel the baby’s first movements (quickening), which is one of the most exciting milestones in pregnancy.
The anatomy scan (detailed ultrasound) happens around week 18–20, where the doctor checks the baby’s organs, growth, and often reveals the gender though many Pakistani families prefer to keep it a surprise. Your pregnancy month calculator would show you’re now in months 4–6, and your appetite will increase significantly during this phase.
Third Trimester (Weeks 28–40)
The final stretch your baby is growing rapidly, gaining about 200 grams per week. You may experience back pain, frequent urination, difficulty sleeping, and Braxton Hicks contractions (practice contractions). By week 36, your doctor will start weekly check-ups to monitor the baby’s position and your blood pressure.
Week 37 onwards is considered full-term. Most Pakistani hospitals recommend having your hospital bag packed by week 35. The baby is now practicing breathing, and the lungs are maturing for life outside the womb. Your pregnancy due date calculator will show the countdown but remember, any delivery between weeks 37–42 is considered normal.
Pregnancy Calculator in Urdu | حمل کا حساب ہفتہ وار
حمل کا حساب لگانے کا سب سے آسان طریقہ یہ ہے کہ آپ اپنی آخری ماہواری کی پہلی تاریخ سے 280 دن آگے شمار کریں۔ اس سے آپ کو اندازاً ڈیلیوری کی تاریخ معلوم ہو جائے گی۔ حمل کو تین حصوں میں تقسیم کیا جاتا ہے: پہلی سہ ماہی (ہفتہ 1 سے 12)، دوسری سہ ماہی (ہفتہ 13 سے 27) اور تیسری سہ ماہی (ہفتہ 28 سے 40)۔ پہلی سہ ماہی میں بچے کے اعضاء بننا شروع ہوتے ہیں اور ماں کو متلی اور تھکاوٹ محسوس ہو سکتی ہے۔ دوسری سہ ماہی میں بچے کی حرکت محسوس ہونا شروع ہوتی ہے اور تفصیلی الٹراساؤنڈ ہوتا ہے۔ تیسری سہ ماہی میں بچے کا وزن تیزی سے بڑھتا ہے اور ڈیلیوری کی تیاری شروع ہو جاتی ہے۔ اپنی ڈاکٹر سے باقاعدگی سے ملتی رہیں اور ہفتہ 35 تک ہسپتال کا بیگ تیار رکھیں۔
Important Prenatal Tests by Week
Knowing when to get tested is just as important as knowing your due date. Here are the key tests your gynecologist in Pakistan will recommend:
Weeks 6–8: First ultrasound to confirm heartbeat and rule out ectopic pregnancy. Weeks 11–13: NT scan (nuchal translucency) to screen for chromosomal abnormalities, plus first blood panel. Weeks 18–20: Anomaly scan — the most detailed ultrasound of your pregnancy, checking every organ. Weeks 24–28: Glucose tolerance test (GTT) for gestational diabetes, which is increasingly common in Pakistan. Weeks 36–40: Weekly non-stress tests (NSTs) to monitor baby’s heartbeat and your contractions.
Tips for Pakistani Mothers at Every Stage
During your first trimester, focus on starting folic acid supplements, staying hydrated, and eating small frequent meals to manage nausea — dry biscuits and chai with ginger work wonders for many Pakistani mothers. In the second trimester, increase your protein and calcium intake through dahi, lassi, eggs, and daal. This is also a great time to stay lightly active with walks.
In the third trimester, prepare your hospital bag, finalize your birth plan with your doctor, and rest as much as possible. Many Pakistani families start preparing the baby’s room and clothes during this phase. Whatever trimester you’re in, avoid self-medicating and always consult your gynecologist before taking any supplements or herbal remedies.
