11 Weeks Pregnant: Your Checklist

  • Consume at least 85 milligrams of vitamin C every day
  • Start learning about breastfeeding and other newborn care topics
  • Start a baby registry

Your little one’s heart has been beating furiously for weeks, but it’s only just become loud enough to hear. A fetus’s heart beats twice as fast as yours, anywhere between 120 and 160 beats per minute. The heart has become a proper four-chambered structure over the last month, although some of the dividing walls won’t be complete until after birth.

A fine layer of skin has been forming over your baby’s body during the last few weeks. Another layer will develop into thicker fingernails and toenails.

Your Baby’s Development

From this week until week 20, your baby will be growing quickly — increasing in size from about 2 inches (5 cm) to about 8 inches (20 cm) from crown to rump. To handle all this growth, the blood vessels in the placenta are growing in both size and number to provide your baby with more nutrients.

Watch Your Baby Grow Facial development continues as the ears move toward their final position on the sides of the head. If you saw a picture of your baby now, you’d think you had a genius on your hands — the baby’s head accounts for about half of the body length!

Although your baby’s reproductive organs are developing rapidly, the external genitals of boys and girls appear somewhat similar until the end of week 11. They will be clearly differentiated by week 14.

Your Body

Nourishing your baby usually requires that you gain weight — and in most cases, the recommended weight gain is 25 to 35 pounds (11.33 to 15.87 kg) over the course of the pregnancy. If you were overweight or underweight before pregnancy, your health care provider may have different recommendations for weight gain.

Your health care provider may offer you a “first trimester screening test.” This combines an ultrasound with a blood test to see whether your baby is at risk for (not whether your baby has) a chromosomal abnormality. An abnormal result does not necessarily mean that your baby has a condition — but more testing might be needed. Talk to your health care provider about the risks and advantages of this test.

Pregnancy symptoms at 11 weeks

If you’ve noticed that you’re leaking wee when you sneeze or run, it’s natural for you to feel worried. But stress incontinence is actually common during pregnancy.

The pregnancy hormones progesterone and relaxin cause your pelvic floor tissues and ligaments to loosen. This can lead to weakness in the sphincter muscles that control the release of wee from your bladder.

The good news is that doing regular pelvic floor exercises will soon put a stop to your leaks. Squeeze your pelvic floor for 10 seconds. Do 10 repetitions, three or four times a day. These exercises can also help your body to prepare for birth, so it’s never too early to start.

What you need to know at 11 weeks pregnant

  • Between now and 14 weeks of pregnancy, you’ll have your dating scan. The main reason for the scan is to work out how many weeks pregnant you are, and to estimate your due date. It will also check if you’re having twins or multiples!
  • Your dating scan can be a very emotional experience. Until now, your pregnancy may have been dominated by managing unpleasant side effects. If you’ve had no side effects at all, it may even be hard to believe you actually are pregnant! So when you get to see your baby, it’s a sudden reminder of the amazing work your body is doing to grow a new life.
  • If you’ve chosen to have a nuchal translucency scan to screen for Down’s syndrome, you’re likely to have this at the same time as your dating scan. Your sonographer will measure a collection of fluid at the back of your baby’s neck and a blood test will be taken. It may take a week or two to get your results back.
