Symptoms can appear from around 6 to 12 days after ovulation when implantation occurs. The earliest signs include implantation bleeding, breast tenderness, fatigue, nausea, and heightened sense of smell. Many overlap with PMS. The only way to confirm pregnancy is a test, ideally on or after the day your period is due.
Implantation happens roughly 6 to 12 days after ovulation. Once it occurs, your body begins producing hCG. Symptoms can start from around implantation, but for many people they do not begin until after the missed period.
Implantation bleeding. Light spotting around 6 to 12 days after ovulation. Lighter than a period, lasts 1 to 2 days.
Cramping. Mild lower abdominal cramping around the time of implantation.
Breast changes. Tender, sore, or swollen breasts. Areolas may darken slightly.
Fatigue. Overwhelming tiredness caused by rising progesterone.
Nausea. Mild queasiness or food aversions driven by rising hCG.
Heightened sense of smell. Suddenly noticing smells that never bothered you before.
Frequent urination. Needing to go more often due to increased blood flow and rising hCG.
Metallic taste. A strange metallic or sour taste in your mouth.
Mood changes. Feeling unusually emotional or irritable.
Bloating. Progesterone slows digestion, causing a feeling of fullness.
A "gut feeling," vivid dreams, and specific food cravings are commonly cited online but not supported by evidence as early pregnancy indicators.
The earliest you can test with reasonable accuracy is the day of your expected period. Test with first morning urine for the highest hCG concentration. A faint positive line means you are almost certainly pregnant. False positives are extremely rare.
Wait 3 days and test again. If your period is more than a week late with negative tests, see your GP.
