What Are the First Signs of Pregnancy?
The earliest and most reliable sign of pregnancy is a missed period. Other early signs include tender breasts, fatigue, nausea, frequent urination, light implantation spotting and a heightened sense of smell — usually appearing within the first few weeks.
The most common first signs
- Missed period — the clearest signal.
- Tender, swollen breasts and darker areolas.
- Fatigue from rising progesterone.
- Nausea (morning sickness), often from week 6.
- Frequent urination.
- Light spotting and cramping from implantation.
- Food cravings or aversions and a sharper sense of smell.
When they appear
Some signs start around implantation (6–12 days after ovulation), but most become noticeable around or after a missed period. Everyone is different, and having few signs is perfectly normal.
Which signs are most reliable
A missed period plus a positive test is the most reliable combination. Individual symptoms like tiredness or sore breasts can also occur before a period, so they are clues rather than proof.
When to test
Take a home test from the day of your missed period for an accurate result.
