By Week 11, you've noticed changes in your skin. Some are welcome, such as your new pregnant glow caused by increased blood volume and oil-producing hormones. However, the same oils may also cause acne. To combat blemishes, wash your face twice a day with a gentle cleanser and switch to oil-free moisturizers and cosmetics. Drink plenty of water to help your body flush toxins. Steer clear of acne medications; some have ingredients that cause birth defects.
As pregnancy progresses, you may notice blotchy discoloration across your nose, forehead, cheeks or body. You can blame hormones for chloasma, also known as "pregnancy mask." Like pregnancy-induced acne, chloasma will go away after your baby is born. In the meantime, reduce or prevent it by wearing sunscreen and avoiding sun exposure. You also can eat more foods containing folic acid, like green leafy vegetables, oranges and whole-grain breads; studies show a folate deficiency contributes to chloasma.
Your uterus is undergoing changes, too. You might feel some twinges as it expands. Blood vessels in your placenta are becoming larger to accommodate the accelerated growth phase your baby is entering. During the next nine weeks, she will triple in length and increase her weight by 30 percent. Right now, though, your baby's still about the length of your thumb from knuckle to tip.
