In the know

The uterus grows from two ounces to about two pounds during pregnancy. In the weeks after birth, it will retreat back into your pelvis and will shrink to almost pre-pregnancy size. Just like snowflakes, every uterus is different.

You may have been told at some point that you have a retroverted uterus. Jennifer, 12 weeks pregnant, asks, "I am 12 weeks pregnant and have just been told I have a retroverted uterus. What does that mean, and am I or the baby at any additional risks?" Find the answer right here.

Coffee cupWhat about caffeine?

Consumed in large quantities, caffeine can cause irritability, nervousness and insomnia. In addition to crossing the placenta and affecting the fetus, it is also a diuretic, dehydrating the mother's body of valuable water.

Even more reason to skip the brew: A study in the American Journal of Obstetrics and Gynecology notes that pregnant women who drink caffeine may double their risk of miscarriage.

"Women who are pregnant or are actively seeking to become pregnant should stop drinking coffee for three months or hopefully throughout pregnancy," said Dr De-Kun Li of Kaiser Permanente Division of Research, who worked on the study. Li also noted that the safest amount of caffeine during pregnancy is "zero amount." Read the full article here.

A vitamin you should take now

As part of doing all you can to protect your baby from birth defects, you should get an extra 400 micrograms of folic acid every day, from either a vitamin supplement or from fortified foods, according to the Institute of Medicine.

Ensure your intake of folic acid (folate) is high from the time you decide to go off birth control until your baby is born, as it helps prevent certain brain and spinal birth defects that affect about 2,500 babies a year. Foods that are naturally rich in folate include citrus fruits, beans and dark green, leafy vegetables.

According to nutritionist Martha Belury, PhD, RD, "Folic acid in a vitamin supplement, when taken one month before conception and throughout the first trimester, has been proven to reduce the risk for an neural tube defect-affected pregnancy by 50 to 70 percent."
