2. Inability to Concentrate

In the first trimester, fatigue and morning sickness can make many women feel worn out and mentally fuzzy. But even well-rested pregnant women may experience an inability to concentrate and periods of forgetfulness. A preoccupation with the baby is partially the cause, as are hormonal changes. Everything — including work, bills, and doctor appointments — may seem less important than the baby and the impending birth. You can combat this forgetfulness by making lists to help you remember dates and appointments.
