What Other Conditions Can Mask the First Signs of Being Pregnant?

Conditions masking early signs of pregnancy can include a missed menstrual period, vaginal discharge and fatigue, states MedicineNet. Symptoms such as headaches and constipation can be considered a distraction or annoyance, and may mask the first signs of pregnancy.

Women with irregular menstrual cycles may not realize a missed period is the hallmark symptom of pregnancy, notes MedicineNet. A thick, murky vaginal discharge, which is normal the first few weeks of pregnancy as the vaginal walls thicken, may be a yeast or bacterial infection and not a sign of pregnancy. Many women experience soreness and fullness of the breasts during the first weeks of pregnancy. This can also be a normal symptom of a menstrual cycle.

Mood changes, common during the first trimester, may not be due to being pregnant, but may be caused by stress and other factors, explains MedicineNet. Frequent urination due to hormonal changes starting the 6th to 8th week of pregnancy can be a sign of a urinary tract infection. Mild cramping and spotting, normal during the time of implantation of the fertilized egg, can be mistaken for a menstrual period.

Bloating in early pregnancy, due to the hormone progesterone, may be considered pre-period bloat rather than a first sign of being pregnant, states EverydayHealth. The best way to confirm a baby is on the way is to take a pregnancy test.
