Pregnancy, week by week
By Dr. Aneela Imran, MBBS · FCPS (Gynae/Obs) updated January 2026.
Pregnancy is not one experience it is three very different ones, stitched together over roughly forty weeks. Here is what most of my patients in Lahore tell me they wish they had known from the start.
First trimester (weeks 1–13)
The quietest trimester from the outside, and the loudest from the inside. Your body is working furiously even when nothing is visible yet.
- What you may feel: exhaustion that feels different to ordinary tiredness, nausea (often worse in the evenings), tender breasts, a heightened sense of smell, and a subtle emotional wobble. All normal.
- What we will do: confirm the pregnancy, set an accurate due date, order a baseline blood panel, start folic acid, and talk about what to expect.
- Eat well enough, not perfectly: small frequent meals, water between (not with) meals, and don't worry if the first trimester is all toast and yogurt. Nutrition catches up later.
- Call me if: bleeding, severe one-sided pain, persistent vomiting (no fluids staying down for 24 hours), or high fever.
Second trimester (weeks 14–27)
For most women, this is the sweetest stretch energy returns, nausea fades, and around week 20 you'll feel those first butterfly movements.
- The big scan: the anomaly scan between weeks 18–22. This is a detailed look at the baby's heart, brain, spine, kidneys, and limbs. If you want to learn the baby's gender, this is when.
- Gestational diabetes screening around weeks 24–28 a simple glucose test. This is important for South Asian women, who carry a higher baseline risk.
- Move daily. Twenty minutes of walking most days is enough. Yoga and gentle stretching help with back pain later.
- Start talking about delivery: where you want to deliver, who you want with you, and any cultural or religious preferences you have. We plan around you.
Third trimester (weeks 28–40)
The home stretch and the longest-feeling weeks of your life. Visits become fortnightly, then weekly, as we monitor growth and prepare for delivery.
- Growth scans at around 32 and 36 weeks to check baby's size and position.
- Hospital bag ready by week 35. (A downloadable checklist is in our resources.)
- Signs of labour: regular, intensifying contractions; water breaking; or a show (mucus plug with light blood). Call us, don't wait.
- Call immediately if: you feel reduced baby movements, sudden severe headache, vision changes, swelling that worsens overnight, or any bleeding.
A gentle closing note
Every pregnancy is different. Your sister's experience is not a template for yours, and the 2 AM WhatsApp forwards from well-meaning aunties should be read with a pinch of salt. Keep in touch with your doctor, take the scans, eat without guilt, rest without apology and trust that your body knows what it is doing.
Ameen. Dr. Aneela
