Before a missed period, symptoms cannot confirm anything - they overlap heavily with PMS - but the common early signs are tender swollen breasts, unusual fatigue, queasiness, frequent urination, smell sensitivity, and light implantation spotting around the due date, per the NHS.
Implantation bleeding gets mistaken for a weak period often. Mood and bloating mean nothing alone. The practical rule: test from the first day of the missed period, when home tests are most reliable, and retest in a few days if negative but the period stays away.

Common questions
What are the early signs of pregnancy before a missed period?
The honest first answer: symptoms alone cannot tell you before a missed period, because the early ones overlap heavily with PMS - only a test can. That said, the signs that commonly show up in the first two weeks, per the NHS and MedlinePlus: swollen or tender breasts (often more intense than the usual pre-period version); unusual, heavy fatigue - rising progesterone is a sedative; queasiness, which can start surprisingly early despite the "morning sickness at 6 weeks" reputation; needing to urinate more often; a heightened sense of smell and new food aversions; and implantation bleeding - light spotting or a very light bleed around the time the period is due, per the NHS, which many people mistake for a weak period. Mood shifts and bloating ride along but mean nothing on their own. The practical rule: none of these confirm anything - test from the first day of the missed period, when the NHS says home tests are most reliable, and retest in a few days if negative but the period stays away.
