Many women notice early pregnancy symptoms before a missed period, often within the first week after conception. Recognising these subtle signs can help you identify pregnancy earlier and begin prenatal care sooner.
Your body starts producing pregnancy hormones immediately after implantation—typically 6–12 days after ovulation. These hormonal changes can trigger noticeable symptoms even before your expected period date.

Understanding Early Pregnancy Symptoms Timeline
The earliest symptoms can appear as soon as 6–8 days after conception, when the fertilised egg implants in the uterine lining. Implantation triggers human chorionic gonadotropin (hCG), the hormone responsible for many early signs.
Unlike typical premenstrual symptoms, early pregnancy indicators often feel different or more intense than your usual monthly changes. Learning the differences can help you recognise pregnancy sooner.
12 Common Early Pregnancy Symptoms
1) Implantation Bleeding and Cramping
Light spotting affects ~25% of pregnant women as the embryo attaches to the uterine wall. It’s lighter and shorter than a normal period (1–3 days) and often pink or brown. Mild, one-sided cramping may occur and tends to feel different from menstrual cramps.
2) Breast Changes and Tenderness
Within 1–2 weeks of conception, rising oestrogen and progesterone can cause fullness, heaviness, and tenderness beyond usual PMS. Areolas may darken and Montgomery’s tubercles (small bumps) can become more prominent.
3) Fatigue and Exhaustion
Up to 90% experience overwhelming tiredness early on. Progesterone surges can make you feel drained by mid-afternoon, regardless of sleep.
4) Nausea and Food Aversions
“Morning sickness” can start 2–3 weeks after conception and isn’t limited to mornings. About 70% report nausea, often with strong food/smell aversions.
5) Frequent Urination
Within 6–8 weeks, increased blood flow to the kidneys and hormonal changes can mean more trips to the bathroom—often without burning or pain (which would suggest a UTI).
6) Elevated Basal Body Temperature
If you chart BBT, a sustained rise for 18+ days post-ovulation is a strong early indicator, as pregnancy hormones keep temperatures high.
7) Mood Changes and Emotional Sensitivity
Early hormonal shifts can bring mood swings, tearfulness, or irritability that feel stronger than typical PMS.
8) Headaches and Dizziness
Hormones and increased blood volume can trigger headaches, sometimes with dizziness or light-headedness—especially if nausea alters eating patterns.
9) Constipation and Bloating
Progesterone slows digestion, causing constipation, gas, and bloating that may exceed your usual premenstrual discomfort.
10) Metallic Taste in Mouth
Dysgeusia—a persistent metallic taste—can alter how foods taste in early pregnancy. It often improves after the first trimester.
11) Increased Vaginal Discharge
Higher oestrogen can increase clear/milky, odourless discharge (leukorrhea). Seek medical advice if discharge has a strong odour, unusual colour, or itching.
12) Sleep Disturbances
Insomnia and vivid dreams are common due to hormonal shifts and early physical changes.
When to Take a Pregnancy Test
Home tests are most accurate after a missed period, though some sensitive tests detect pregnancy 6–8 days before your expected date. Testing too early can yield false negatives. For the most reliable result, test at least one day after your missed period; if negative but you still suspect pregnancy, retest in a few days. Blood tests at a clinic can detect pregnancy earlier and more accurately.
Distinguishing Pregnancy Symptoms from PMS
Many signs overlap with PMS, but pregnancy symptoms often start earlier and feel more pronounced. Implantation bleeding is unique to pregnancy. Track your symptoms to spot deviations from your normal pattern and share details with your healthcare provider.
FAQ: Early Pregnancy Symptoms
How early can pregnancy symptoms start?
As early as 6–8 days after conception (post-implantation). Many notice symptoms around 4–6 weeks, near the time of a missed period.
Can you have pregnancy symptoms before implantation?
No—true pregnancy symptoms require hormones released after implantation.
Are early symptoms the same for everyone?
No—symptoms vary widely between women and even between pregnancies.
What should I do if I think I’m pregnant?
Take a home test after your missed period and book a visit with your provider to confirm and begin prenatal care.
When should I be concerned?
Seek care for heavy bleeding, severe cramping, persistent vomiting, or any worrying symptoms. Early prenatal care matters.
