How can I tell if my symptoms are from pregnancy or PMS?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Pregnancy and PMS share many overlapping symptoms, making them difficult to tell apart. However, key differences exist: pregnancy typically involves a missed period, nausea (morning sickness), and breast tenderness that persists, while PMS is more commonly associated with mood swings, bloating, and cramping that resolve once your period begins. Fatigue and food cravings can occur with both, but they tend to be more intense and longer-lasting in early pregnancy.

Because these symptoms overlap so closely, guessing can lead to unnecessary stress or delayed care. The fastest way to gain clarity is to take a free, instant, online symptom check. In just a few minutes, you'll receive personalized insights based on your specific symptoms, helping you understand what may be going on and what steps to take next—whether that's taking a pregnancy test, scheduling a doctor's visit, or simply monitoring how you feel.

Pregnancy and PMS (premenstrual syndrome) can sometimes feel similar, but there are key differences. Pregnancy Symptoms: These can start early and include nausea, a missed period, and breast tenderness. You might also feel tired and need to urinate more often. PMS Symptoms: These usually happen before your period and can include mood swings, bloating, and cravings. You might feel irritable or have physical discomfort like cramps.

Key Differences:

Pregnancy: Look for signs like nausea and a missed period.
