Is my girlfriend gaining weight or is she pregnant because not experiencing any symptoms of pregnancy except fatigue and bigger breasts which one she?

Pregnancy symptoms can vary widely from woman to woman, and some women may experience only mild or no symptoms in early pregnancy.

- Fatigue is a common symptom of both pregnancy and weight gain, so it's not a reliable indicator on its own.

- Breast enlargement is also common in both pregnancy and weight gain, and it can be difficult to tell the difference.

Other possible signs of pregnancy include:

- Missed period

- Nausea and vomiting

- Frequent urination

- Darkened nipples and areolas

- Bloating

- Constipation

- Mood swings

If your girlfriend is experiencing any of these other symptoms, it's possible that she is pregnant. However, the only way to know for sure is to take a pregnancy test.
