If you leak urine throughout the day, wearing panty liners will make you more comfortable. The increased production of the hormones estrogen and progesterone is the primary reason for the changes in a pregnant woman's breasts. By a few weeks of gestation, you may notice tingling sensations in your breasts, and they may feel heavy, tender, and sore. A good support bra can help alleviate breast soreness. If you have large breasts that make you uncomfortable at night, you might want to try wearing a bra while you're sleeping too.
Occasional headaches trouble many women in early pregnancy.
The cause is uncertain, but like so many other discomforts of the first trimester, changes in your hormone levels and blood circulation may be factors. Other possible causes are the stress and fatigue that often accompany the emotional and physical adjustments to pregnancy. If you suddenly eliminated or cut down on caffeine once you learned you were pregnant, this change may also cause headaches for a few days. Dizziness is common in pregnant women and can result from circulatory changes during pregnancy. Stress, fatigue, and hunger can also be causes of dizziness or faintness.
