Early pregnancy signs vs PMS

They overlap. A test and a clinician beat any symptom checklist.

The overlap

Tiredness, sore breasts, mood shifts, and a late period can belong to either PMS or early pregnancy. Implantation spotting is not something you can confirm from an app.

What actually answers the question

A home pregnancy test after a missed period, repeated if needed, and a conversation with a clinician. If you have pain, heavy bleeding, or feel unwell, seek care rather than waiting on a prediction.
