Your Baby's Development: Week 11

Week 11
You are now 11 weeks pregnant and may already be concerned about weight gain! However, to nourish your baby, you must gain some weight. If you are concerned about gaining too much weight, simply follow a balanced, healthy diet and exercise.

Pregnancy Tip

As you get closer to the second trimester, your nutritional needs change. That's why Biotegrity has designed their to fulfill your needs at different stages of pregnancy. Get more of what you need now, like folic acid, and less of what you don't.

For most women, it is recommended that they gain somewhere between 25 to 35 pounds during their pregnancy. This is caused by the placenta, an increase in blood volume, the amniotic fluid, an enlarged uterus and expanded breasts - and, of course, the weight of the baby! See our chart for a breakdown of weight gained during an average pregnancy.

How Much Weight Is Too Much?
During the first trimester, a woman gains around 2 to 5 pounds. In the second trimester, this is increased to 13 pounds overall weight gain. And in the third trimester, she gains 11 pounds. If a woman is either overweight or underweight, her health care provider may have different expectations for weight gain.

How Does My Baby Look?
This week, your baby weighs around 8 grams. Baby's head takes up half of the baby's size right now. At this point, you baby's irises will start to develop and tiny finger nails are visible.

This is a stage of rapid growth. From Week 11 up until Week 20, baby grows in size from around 1.7 to 2.4 inches (that is 44 to 60 mm) and 0.3 ounces (8 grams) to just over 6 inches (about 16 centimeters) and 10.5 ounces (or 300 grams).

Boy or Girl?
Baby's reproductive organs also develop very quickly at this stage, so by the end of this week, the external genitalia are recognizable! Blood vessels in the placenta increase in size and number to accommodate all this growth and to provide your baby with more nutrients.
