Week 7 of pregnancy: Rapid Growth
Brain regions form and hands begin to take shape. A practical Indian guide to food safety in pregnancy: milk, paneer, eggs, fish, papaya and street food.
Last updated 28 September 2026
What's happening this week?
The embryo's brain is growing faster than any other part, and the first outlines of hands, feet and eyes are forming. For you, nausea and tiredness may be at their most draining, and some people also notice a lot of extra saliva. This is a good week to review how food is bought, stored and cooked at home, because a few infections spread through food are more serious in pregnancy. Most everyday Indian meals are fine; the changes needed are small and specific.
Baby's development
Brain growth is the headline this week. The front part of the neural tube, which closed in week 6, swells and divides into five secondary brain vesicles. These are the foundations of the main parts of the brain, which will keep developing throughout pregnancy and for years after birth.
At the ends of the limb buds, flat hand plates form, followed by foot plates. The lens and the early retina begin to form in each eye. The heart, until now a looping tube, starts to divide into separate chambers, a process that continues through weeks 8 and 9.
Weeks 3 to 10 are the most sensitive time for the development of major structures, which is one reason avoiding alcohol and checking every medicine matters so much now.
Some week-by-week sites say bones are already replacing cartilage at this point. That is overstated: bone formation begins at around 8 to 9 weeks and continues for years. On a transvaginal scan, cardiac activity is reliably seen in an ongoing pregnancy once the embryo measures 7 mm or more.

Gestational age
The 1.3 cm shown here sits just above the usual range: embryos at 7 weeks typically measure about 7 to 12 mm from crown to rump. They grow so quickly now that a few days' difference in dates changes the figure noticeably. The blueberry is a loose comparison, not a target your embryo should match.
Your body this week
hCG keeps rising towards its peak at about 8 to 11 weeks, and nausea often builds towards its own peak at around 9 weeks, so many people find these weeks among the hardest of early pregnancy. Your blood volume has also started to rise, and needing to pass urine more often is still common.
Some people produce much more saliva than usual, or find that swallowing it makes them feel sick. It is not harmful. Sipping water, rinsing your mouth and spitting into a tissue when you need to can make it more bearable, and it tends to settle as nausea eases.
Your womb is larger than before pregnancy but still sits low in the pelvis, so nothing shows yet. Bloating can make waistbands feel tight, and progesterone may leave you constipated. Tiredness is often at its heaviest, so where your day allows, a short rest in the afternoon is worth protecting.
Symptoms you may notice
Every pregnancy is different - you may have some, all or none of these.
- Nausea and vomiting
- Often nearing its peak. Keep up small, frequent snacks and sips of fluid. If fluids will not stay down for about 24 hours, contact your doctor the same day.
- Extra saliva
- Some people notice a lot more saliva, often alongside nausea. It is not harmful. Sipping water and rinsing or spitting as needed can make it easier to live with. Keep a small tissue pack or cup with you when you go out.
- Bloating
- Linked to progesterone. Smaller meals, eating slowly and a gentle walk after food may help.
- Tiredness
- Still very common. Indian dietary guidelines suggest regular daytime rest in pregnancy, so lie down for a while when you can.
- Heightened smell
- Kitchen smells may still bother you. Cold meals, good ventilation and sharing the cooking can help, and many people find this eases later in the first trimester.
Medical care and tests
Thalassaemia and sickle cell screening
Varies by providerIdeally before 8 to 10 weeks
These inherited blood conditions are screened for with a blood test. An Indian expert guideline recommends thalassaemia screening at the first visit, ideally before 8 weeks, with your partner tested at the same time. In the UK the screen is usually done before 10 weeks. Early results leave time to discuss further tests if both parents carry the trait.
Early scan if not yet done
Commonly offered6 to 9 weeks in many Indian clinics
If your doctor recommends one and you have not had it, a scan now should show the embryo and its cardiac activity, and help confirm your dates.
Td vaccine
RoutineAt registration, early in pregnancy
India's national schedule gives two doses of Td (tetanus and diphtheria) vaccine in pregnancy, the first early on and the second four weeks later, or a single booster if you had two doses in a pregnancy within the last three years.
The food safety advice on this page draws on Indian (ICMR-NIN) and UK (NHS) guidance. Your doctor may tailor it to your own health.
Nutrition this week
- Milk and paneer: boil loose milk or use pasteurised packaged milk. Paneer made from pasteurised or boiled milk is safe; be wary of paneer of unknown origin, especially uncooked, and cook it until steaming hot if unsure. Avoid mould-ripened and blue soft cheeses unless cooked until steaming.
- Eggs and meat: eat eggs only when white and yolk are firm, so no runny half-fry, homemade mayonnaise or raw-egg desserts. Cook chicken and meat until no pink or blood remains, reheat cold cured meats until steaming, and avoid liver, which is very high in vitamin A.
- Fish: avoid shark, swordfish and marlin because of mercury, limit tuna, and skip raw fish. Sardine (mathi), mackerel (bangda), rohu and katla are good choices, with up to two portions of oily fish a week.
- Papaya: avoid unripe or semi-ripe papaya, including kacchi papaya sabzi and salads, and papaya seeds, latex or leaf extracts.
- Street food and produce: choose freshly cooked, piping-hot dishes over pre-cut fruit, uncooked chutneys, raw salads and pani-puri water of unknown hygiene. Wash all produce, steam sprouts, and drink boiled or filtered water.
Movement and exercise
- Keep moving gently if you can. A short walk after a meal may ease bloating for some people.
- Prenatal yoga is fine at this stage. Avoid lying on your belly, deep twists, inversions and hot rooms.
- Listen to your energy. On days when nausea is bad, a few minutes of stretching still counts, and rest is not a failure.
- If you play a contact sport, now is the time to switch to something with less risk of falls or blows.
Things to keep in mind
- Listeria, a bacterium found in some chilled and unpasteurised foods, is more likely to cause infection in pregnancy and can lead to miscarriage or serious illness in a newborn. Heating food until steaming hot kills it.
- Reheat leftovers until they are steaming hot all the way through.
- Herbal teas: keep to about four cups a day at most, and avoid liquorice-root tea.
- Indian dietary guidelines say there is no need to avoid foods because of traditional taboos. If relatives suggest cutting out a healthy food, check with your doctor.
- Wear gloves for gardening and wash your hands after handling soil or raw meat.
When to contact your doctor
Call your doctor or midwife the same day if you have
- A fever of 38°C or more, or feeling hot and shivery.
- Not keeping fluids down for about 24 hours.
- Any spotting or bleeding.
- Pain or burning when you pass urine.
Get emergency care now if you have
- Heavy bleeding or passing clots.
- Tummy pain on one side with dizziness, fainting or shoulder-tip pain.
- Vomiting with confusion, fainting or blood in it.
- Severe, constant tummy pain.
In India, call 108 for an ambulance, 102 for free transport for pregnant women in many states, or 112 for any emergency - or go straight to your nearest hospital with a maternity unit.
If something feels wrong, trust that feeling and call - you never need to wait for your next appointment.
Questions to ask your doctor
- Is the milk and paneer we buy at home safe as it is?
- Which fish are safe for me, and how often?
- Do I need a thalassaemia test, and should my partner be tested?
- When is my Td vaccine due?
Week 7 checklist

- Swap runny eggs for fully cooked ones
- Take raw papaya dishes off the menu
- Wash produce and steam sprouts
- Ask about thalassaemia screening
Frequently asked questions
Is papaya safe in pregnancy?
Ripe papaya, eaten in normal food amounts, is generally considered fine. The concern is with unripe or semi-ripe green papaya, whose latex made the womb contract in animal and laboratory studies. Good human studies are lacking either way, so the cautious approach is to avoid raw papaya dishes, papaya seeds, latex and leaf extracts, and enjoy ripe papaya as a fruit.
Can I eat paneer while pregnant?
Yes, if it is made from pasteurised or boiled milk. Packaged paneer made from pasteurised milk, or paneer made at home from boiled milk, is a good protein source. Be more careful with loose paneer of unknown origin, particularly in uncooked dishes; cooking it until steaming hot lowers the risk. Avoid mould-ripened and blue soft cheeses unless they are cooked.
Is street food safe during pregnancy?
It can be, with care. Freshly cooked, piping-hot food served straight from the pan is the safer choice. Pre-cut fruit, uncooked chutneys, raw salads and pani-puri water are riskier because you cannot be sure of the hygiene or the water used. Carry your own boiled or filtered water when you are out.
