Being 7 weeks pregnant covers days 49–55 after the first day of your last period (7+0 to 7+6 weeks), and you are in the 2nd month of pregnancy. Your baby is about 10 mm from head to bottom; the brain is growing faster than the body, and hands are starting to appear at the ends of the arm buds. The blood tests of the first antenatal visit usually come up around now.
About 1 month and 19 days have passed since the first day of your last period; 7 weeks pregnant is in the 2nd month of pregnancy.
According to the NHS, your baby is about 10 mm long from head to bottom, about the size of a grape. Because the brain is growing faster than the rest of the body, the forehead is large. There are small dimples where the nose and ears will be, and the eyelids are starting to grow over the eyes.
The limb buds are forming cartilage, which will become the bones of the arms and legs. The arm buds are getting longer, and their flattened ends will soon become tiny hands. The brain and spinal cord are taking shape quickly: the NHS says the embryo makes around 100 new brain cells every minute.
The amount of blood circulating in your body is increasing; according to the NHS, blood volume rises by up to 50% over the course of pregnancy. The extra blood feeds the womb, but it can make you thirstier than usual. The NHS suggests drinking 8 medium glasses of fluid a day (water, fruit tea, fruit juice, skimmed or semi-skimmed milk).
Your womb is now about the size of a lemon. If this is your first pregnancy, your bump probably will not show until around week 12; if you have had a baby before, it may show sooner (NHS).
Nausea, tiredness and mood swings can make this week hard. A metallic taste, sore breasts, headaches, a heightened sense of smell and mild cramps are also common. The NHS stresses that most aches and pains are a sign of a normal pregnancy, but unusual symptoms such as feeling itchy all over should not be ignored.
The first antenatal visit takes place within the first 14 weeks according to the Turkish Ministry of Health guideline, and by 10+0 weeks according to NICE. The tests offered at this visit largely overlap between organisations, with some differences. In the table below, “—” means the test does not appear in that organisation's first-visit or early-pregnancy list (sources checked: the first-visit section and viral hepatitis algorithm of the Turkish Ministry of Health guideline; NICE NG201 recommendations 1.2.12–1.2.13 and the appointment schedule, and NICE NG3 for blood sugar; the ACOG routine tests patient FAQ).
| Test | Turkish Ministry of Health (2026) | NICE NG201 (2021) / NG3 | ACOG patient FAQ (FAQ133, 2026) |
|---|---|---|---|
| Full blood count | Yes | Yes | Yes |
| Blood group and Rh | Yes; the partner's blood group is also checked | Yes | Yes |
| Urine | Urinalysis and urine culture | Urine dipstick for protein | Urinalysis and urine culture |
| Hepatitis B | Yes (even if vaccinated) | Yes | Yes |
| Hepatitis C | Yes (anti-HCV) | — | Yes |
| Syphilis | Yes | Yes | Yes (3 times in pregnancy) |
| HIV | Yes (with the woman's knowledge and consent) | Yes | Yes |
| Rubella immunity | If immunity is unknown | — | Yes |
| TSH (thyroid) | Yes | — | — |
| Sickle cell / thalassaemia | Thalassaemia screening if MCV is low without iron deficiency | Yes | — |
| Chlamydia and gonorrhoea | — | — | If under 25 or at increased risk |
| Blood sugar | At the first visit if in a risk group | Glucose tolerance test at 24–28 weeks if at risk; as soon as possible after booking if you had gestational diabetes before (NG3) | In the first trimester if at risk |
If your blood group is Rh negative: according to the Turkish Ministry of Health guideline, if the mother is Rh negative and the father Rh positive, an indirect Coombs test is done; if negative, it is repeated at 28 weeks, and if positive, the woman is referred to a specialist centre. ACOG also notes that Rh-negative women may be given medicine during pregnancy to prevent antibodies from forming. See our Rh disease guide for details.
The embryo usually becomes measurable at 6 to 7 weeks. The crown-rump length (CRL) measured at this stage is the best measurement for setting the due date up to 8+6 weeks, accurate to ±5 days (UpToDate, 2026). The NHS also notes that your due date is set more accurately by a dating scan, usually done at 8 to 14 weeks.
| Symptom | Usually | Seek care if |
|---|---|---|
| Thirst and needing to pee often | Increased blood volume can make you thirsty; needing to pee more is a common first-trimester symptom (NHS). | Go to the emergency department if you cannot keep food or fluids down for more than 12 hours, feel dizzy when standing or are passing much less urine (UpToDate). |
| Pelvic cramps | Mild cramps a bit like period pains are common in the first trimester (NHS). | Pain on one side, pain that keeps getting worse or pain with bleeding needs checking; for sudden severe pain, feeling faint or shoulder-tip pain, go to the emergency department. Ectopic pregnancy symptoms typically appear 6–8 weeks after the last period (UpToDate). |
| Spotting or bleeding | Bleeding is common in the first trimester and most women who bleed do not miscarry (UpToDate), but because it also occurs with miscarriage and ectopic pregnancy it is not treated as normal. | The NHS advises seeing a doctor for any bleeding; do not wait if it is heavy or comes with pain. |
Most of these are danger signs or emergency referral criteria in the Turkish Ministry of Health guideline; the ectopic pregnancy signs and the 12-hour threshold for severe vomiting are based on UpToDate (UpToDate, 2026). The NHS also advises seeing a doctor for any bleeding in pregnancy. Contact your doctor or go to the nearest emergency department without waiting; for sudden severe abdominal pain, fainting or shoulder-tip pain, go straight to the emergency department.
Being 7 weeks pregnant is about 1 month and 19 days since the first day of your last period, which counts as the 2nd month of pregnancy.
According to the NHS, about 10 mm from head to bottom, about the size of a grape. The crown-rump length (CRL) measured on ultrasound at this stage is the most accurate way to set the due date (UpToDate, 2026).
Usually not. Your womb is about the size of a lemon this week. In a first pregnancy, your bump probably will not show until around week 12; if you have had a baby before, it may show sooner (NHS).
According to the Turkish Ministry of Health guideline: full blood count, blood group (yours and your partner's), urinalysis and urine culture, hepatitis B and C, syphilis, HIV (with your consent), TSH and, if needed, rubella immunity; blood sugar is also checked if you are in a risk group. The NICE and ACOG lists are largely similar; the differences are shown in the table above.
According to the Turkish Ministry of Health guideline, if your partner is Rh positive, an indirect Coombs test is done; if negative, it is repeated at 28 weeks, and if positive, you are referred to a specialist centre. If you have any bleeding in pregnancy, always tell the doctor you see that you are Rh negative.
