What’s the Difference Between Early Pregnancy Symptoms and Premenstrual Symptoms?

March 7, 2025

If you’re feeling different than usual and wondering whether you might be pregnant, it can be difficult to tell the difference between early pregnancy symptoms and premenstrual symptoms—since many of the signs can overlap, leading to confusion.

Read on to understand the key differences and some next steps. Or, if you’re looking for complimentary pregnancy testing, reach out to Women’s Care Center today for a confidential appointment.

Similarities Between Pregnancy and PMS Symptoms

Both early pregnancy and premenstrual syndrome (PMS) can cause:

• Breast tenderness – Increased hormones during early pregnancy and premenstrual syndrome can lead to sore, swollen, or sensitive breasts.
• Fatigue – Hormonal changes in both pregnancy and PMS can make you feel more tired than usual.
• Mood swings – Fluctuating hormone levels may lead to increased emotional sensitivity.
• Cramping – Some women experience mild cramping as an early pregnancy symptom, similar to period cramps.
• Food cravings or aversions – Hormonal shifts can cause changes in appetite and food preferences.

Key Differences Between Pregnancy and PMS

While there are many similarities, there are also distinct differences between PMS and pregnancy symptoms:

• Missed period – The most telling sign of pregnancy is a missed period. If your period is late, it’s time to take a pregnancy test.
• Implantation bleeding – Some women experience light spotting a few days before their expected period, which could be implantation bleeding rather than a normal period. If what you believe to be your period feels extra light, it could be implantation bleeding instead.
• Nausea with/without vomiting – While PMS does not typically cause nausea, early pregnancy symptoms often include morning sickness or queasiness.
• Increased urination – Pregnant women may find themselves needing to use the bathroom more frequently due to hormonal changes.

Taking the Next Step: Pregnancy Testing

If you’re experiencing symptoms and are unsure whether they are due to pregnancy or PMS, taking a pregnancy test is the best way to find out. Pregnancy tests detect the hormone hCG, which is only present during pregnancy.
