What is the difference between PMS and pregnancy symptoms?

Premenstrual syndrome (PMS) and pregnancy symptoms can be very similar, making it difficult to tell them apart. Here is a table comparing some of the most common symptoms of PMS and pregnancy:

| Symptom | PMS | Pregnancy |

|---|---|---|

| Breast tenderness | Common | Very common |

| Bloating | Common | Common |

| Mood swings | Common | Less common |

| Headache | Common | Less common |

| Fatigue | Common | Very common |

| Nausea | Less common | Very common |

| Vomiting | Rare | Less common |

| Constipation | Common | Less common |

| Diarrhea | Less common | Less common |

| Spotting | Less common | Less common |

| Missed period | Not a symptom | A sign of pregnancy |

If you are experiencing any of these symptoms and are not sure whether you are pregnant, it is important to take a pregnancy test. A pregnancy test can detect the presence of human chorionic gonadotropin (hCG), a hormone produced by the body during pregnancy. Pregnancy tests are available over the counter at most pharmacies.

If you are pregnant, it is important to see a doctor to begin prenatal care. Prenatal care can help you and your baby stay healthy during pregnancy.
