Early signs of pregnancy before a missed period can include:
- Fatigue and unusual tiredness due to increased progesterone and energy demands of supporting a fetus.
- Nausea and morning sickness that may start early and is distinct from regular illness.
- Spotting or light bleeding known as implantation bleeding, occurring when the fertilized egg attaches to the uterine lining — usually lighter and shorter than a period.
- Breast changes such as tenderness, swelling, or soreness caused by hormone changes.
- Mild cramping similar to menstrual cramps.
- Increased urination frequency.
- Heightened sense of smell and food aversions.
- Mood swings and sensitivity.
These symptoms often appear about a week before a missed period but can vary greatly among women. The most definitive early sign remains a missed period itself, but some women notice these symptoms before that time.
