15 early signs of pregnancy
The symptoms that arrive before a missed period, which ones could be something else, and how antenatal care and costs work in Singapore.
A missed period is the clearest early sign, and it is rarely the first one noticed. Tender breasts, sudden tiredness, nausea, food aversions and needing the toilet more often usually arrive before it. None of them confirms anything. A home test taken from the day your period is due does.
Which early signs come first?
Breast tenderness and fatigue tend to lead. Both are driven by rising progesterone, and both can start within a week or two of conception, well before a period is late.
Nausea follows for most women. The NHS lists sickness among the common symptoms of early pregnancy, and ACOG describes nausea and vomiting as one of the most frequent complaints of the first trimester. It usually eases by the second.
The frustrating part is that nothing on the list is specific. Sore breasts, tiredness, cramping and mood changes are also what the week before a period feels like. Any symptom this early tells you only that a test is worth buying, and Guardian, Watsons and Unity all stock them without a prescription.
All 15 early signs of pregnancy
| Sign | Why it happens | What helps |
|---|---|---|
| Missed period | hCG from the implanted embryo stops the cycle | Take a test from the day it was due |
| Breast tenderness and swelling | Rising progesterone; areolas may darken | A soft wire-free bra, nipple balm for dryness |
| Fatigue | Progesterone, plus organs working harder | Earlier nights, less caffeine |
| Nausea and vomiting | Rising hCG, often worse on an empty stomach | Small frequent meals, dry crackers, ginger |
| Food aversions | Heightened sense of smell | Eat what stays down; nutrition can wait a few weeks |
| Food cravings | Not fully understood, probably hormonal | Fine, within the list of foods to avoid |
| Heightened sense of smell | Hormonal | Keep windows open; avoid the lift after lunch |
| Constipation | Progesterone slows the gut | Fibre, fluids, movement |
| Spotting | Implantation in the uterine lining | Mention any bleeding to a doctor |
| Excess saliva | Often paired with nausea | Brush often; rinse with water |
| Mild cramping | The uterus beginning to change | Warm shower, gentle stretching |
| Raised basal temperature | Elevated progesterone | Nothing; it settles |
| Mood swings | Hormones, plus the news itself | Say it out loud to someone |
| Dizziness | Blood pressure shifts, low blood sugar | Small regular meals, stand up slowly |
| Frequent urination | More blood volume, kidneys filtering more | Keep drinking; do not cut fluids |
A few of those behave differently in this climate. Dizziness arrives faster when you are dehydrated, and walking to the MRT at midday in 33°C does that quickly. Frequent urination plus heat means you need more water, not less, however inconvenient the toilet trips become.
Which of these could be something else?
Worth knowing, because a few symptoms deserve a different conversation.
Severe, persistent vomiting that stops you keeping fluids down is not ordinary morning sickness. The NHS calls it hyperemesis gravidarum and it needs treatment, sometimes admission for a drip. Weight loss, dark urine and dizziness alongside the vomiting are the markers. Our guide to pregnancy nausea remedies covers the manageable end of the spectrum.
Dizziness with palpitations and breathlessness can point to anaemia, which is common here and easily tested. Vaginal discharge that is green, grey, frothy or foul-smelling is an infection rather than the normal increase. And a missed period with a negative test, repeated, deserves a doctor's opinion rather than more tests.
What should you do if the test is positive?
Four things, in this order.
Start folic acid if you have not already. HealthHub and the Health Promotion Board recommend it before conception and through early pregnancy, because it reduces the risk of neural tube defects. Pharmacies sell it over the counter.
Book an antenatal appointment. Early, not after the first trimester.
Stop what needs stopping. Alcohol, smoking, and the foods on the avoid list. Our guide to foods to avoid in pregnancy has the Singapore-relevant version, including raw seafood and unpasteurised dairy.
Check your medicine cabinet. Bring everything you take, including supplements and skincare actives, to the first appointment.
How does antenatal care work in Singapore?
Polyclinics provide antenatal care for low-risk pregnancies at subsidised rates, and refer onward when something needs specialist attention. KKH and NUH both run obstetric services you can go to directly, as do private obstetricians.
On cost: the Ministry of Health's MediSave Maternity Package allows MediSave to be used for pre-delivery expenses, including consultations, scans and tests, as well as the delivery, within published limits. After the birth, the Baby Bonus Scheme from the Ministry of Social and Family Development provides a cash gift and a Child Development Account with government co-matching. Reading both schemes in the first trimester is less stressful than reading them in the third.
Your first visit will confirm the pregnancy, date it by scan, and set the schedule of appointments. Our trimester timeline sets out what happens when, and staying comfortable during pregnancy covers the practical adjustments.
Which symptoms need a doctor now?
Some things do not wait for the next appointment.
Go to A&E straight away for heavy vaginal bleeding, severe one-sided abdominal pain, shoulder-tip pain, fainting, or pain with bleeding in the first weeks, which can be signs of an ectopic pregnancy. Call 995 if you collapse or feel faint and unwell. See a doctor the same day for a fever above 38°C, burning on urination, or vomiting that has stopped you drinking for a day.
For everything else, write it down and bring the list. Mood that stays flat for more than a fortnight belongs on that list too; our piece on pregnancy mood covers the ordinary version, and a doctor covers the rest.
Frequently asked questions
- When is a home pregnancy test reliable?
- From the day your period is due, which is when most kits reach their stated accuracy. Testing earlier can give a false negative because there is not yet enough hCG in your urine. Use the first urine of the morning if you are testing early, and retest in a few days if the result is negative and your period still has not come.
- Can you have pregnancy symptoms before a missed period?
- Yes, and most women do. Tender breasts, tiredness, nausea, heightened sense of smell and needing the toilet more often can all start in the week or two after conception. They overlap almost completely with premenstrual symptoms, which is why a test matters more than a symptom list.
- Is spotting in early pregnancy normal?
- Light spotting around the time of implantation is common and usually harmless. Any bleeding in pregnancy should still be mentioned to a doctor, because the NHS advises getting bleeding checked to rule out other causes. Heavy bleeding with cramping needs same-day attention.
- Where do I go for my first antenatal visit in Singapore?
- Polyclinics provide antenatal care for low-risk pregnancies and will refer you onward if needed. You can also go directly to KK Women's and Children's Hospital, the National University Hospital, or a private obstetrician. Book once a test is positive rather than waiting for symptoms to settle.
- Does MediSave cover pregnancy costs?
- Partly. The Ministry of Health's MediSave Maternity Package lets you use MediSave for pre-delivery expenses such as consultations, tests and scans, and for the delivery itself, within set limits. The Baby Bonus Scheme adds a cash gift and a Child Development Account after the birth.
