Common symptoms and signs of a pregnancy include morning or all-day sickness with nausea, exhaustion, sensitivity to scents, frequent urination and enlarged breasts, according to WebMD. Additional symptoms may include an itchy abdomen, constipation, heartburn and changes in balance.
Some pregnant women may experience unpredictable seasonal allergies or symptoms of asthma during pregnancy, explains WebMD. In some cases, allergy symptoms may cease during pregnancy, while some women experience enhanced allergies. Fatigue during pregnancy can trigger additional symptoms, such as forgetfulness, a lack of organization and a lack of focus when completing multiple tasks.
Although pregnancy symptoms may vary based on the age, health condition and emotional well-being of the mother-to-be, women should be concerned about any abnormal symptoms, such as spotting or bleeding in the second and third trimester, warns WebMD. In addition, severe itching in the late second and third trimesters may indicate the development of rare liver problems. Additional symptoms of concern include severe headaches, pain in the right side of the abdomen and blurred vision, which can indicate preeclampsia, a medical condition in which blood pressure increases to a dangerously high level. Any abnormal pregnancy symptoms should be reported to a physician immediately to secure the well-being of the baby and the mother.
