What Are Common Symptoms During the First Month of Pregnancy?

Symptoms during the first month of pregnancy include a missed period, swollen breasts, nausea, increased urination, fatigue, cramping and mood swings, notes Mayo Clinic. While these symptoms may exist, the only method of diagnosing pregnancy is through a pregnancy test, states WebMD.

Pregnancy triggers hormonal changes throughout the body that lead to unique symptoms, explains Mayo Clinic. Breasts can become swollen and feel heavier than usual. During pregnancy, levels of the hormone progesterone increase, and this biological change can lead to fatigue. Hormonal changes can also make a woman emotional and weepy.

Not all women experience the same symptoms during pregnancy, says WebMD. In some instances, pregnancy symptoms are similar to symptoms experienced before and during menstruation. When pregnant, a woman may feel cramping due to a fertilized egg attaching itself to the wall of the uterus. In addition, vaginal discharge is possible.

If experiencing symptoms, a woman can either administer a home pregnancy test or undergo a blood examination from a medical practitioner, according to Sasha Emmons for Parenting.com. Home tests are available for purchase at pharmacies and grocery stores, notes Dr. Robin Elise Weiss for About.com. Blood tests offer more detailed results regarding the health of the pregnancy and are usually more expensive. Both home tests and blood tests measure hCG, or human chorionic gonadotropin.
