Pregnancy week by week



Week 11 of Pregnancy

You are almost through the first trimester. This week you may be due for your scan, if it has not been done earlier. A scan can give a pretty accurate estimate of how far your pregnancy has progressed and when your baby’s due, and show how your baby’s developing.

Your doctor may also suggest that you get a screening test done to rule out chromosomal abnormalities like Down syndrome. This screening test is done between 11-13 weeks of pregnancy. It involves a scan and a blood test.  The blood test will measure your levels of two pregnancy hormones hCG and PAPP-A. And ultrasound will be done to measure the fluid under the skin of your baby’s neck (nuchal translucency). The result of the blood test and ultrasound along with your age can help your doctor calculate the odds that your baby has a chromosomal abnormality.

It is important to keep in mind that this is only a screening test. If your tests come positive, your doctor will suggest additional tests such as amniocentesis to confirm or rule out the diagnosis. Refer to our section on antenatal tests to read more.

Your body

As you approach the end of your first trimester, you may still have symptoms like morning sickness, tiredness and frequent urination. These discomforts will likely continue into the next week and possibly into your second trimester. One of the best ways to recover your lost energy is to take some regular exercise. It can also strengthen your muscles to help you carry the extra weight, improve your joints, and make it easier for you to give birth to your baby. Swimming, yoga and walking are all good pregnancy exercises. Refer to our fitness section to learn more.

You probably haven’t gained much weight so far, you may be feeling a little concerned about your weight gain. However, everyone is different and many women actually lose weight from morning sickness. It is important to remember that good nutrition is important for both you and your baby. Remember to take your prenatal vitamins, eat lots of fruits, vegetables and get plenty of proteins.  Around this time, many women will start experiencing more heartburn. It happens as the uterus expands and presses up against the abdomen and also because of an increase in the hormone progesterone. This hormone will relax the valve between the stomach and oesophagus resulting reflux of stomach acid into the oesophagus. Here are some suggestions to relieve and prevent heartburn.
  • Eat smaller meals and have six meals a day instead of three

  • Ensure you chew your food well and eat slowly.

  • Drink liquids before and after your meals and not with them

  • Stay away from fizzy drinks, citrus juices and spicy meals.

  • Do not eat 2 to 3 hours before going to bed

  • Avoid foods that aggravate your symptoms, such as spicy, fatty and greasy foods which will only make the problem worse.

  • Raise the head of your bed or pop yourself up with pillows and lie on your left side.
  • Wear loose fitting clothes

Your baby

Your baby measures 5 cm in length. Your baby is now as long as your little finger. Your baby’s vital organ systems are now developed and he has a skeleton, nerves and blood circulation. His spine has fused and has tiny feet that are fully formed. The baby’s eyelids are fused now and the irises are developing. Your baby will also begin to get baby teeth, fingernails, toenails, and hair follicles this week

Because the most critical part of your baby’s development is now over, the probability of any pre- natal defects is reducing. The rest of the pregnancy for your baby will be about rapid growth, organ maturation and getting ready for delivery.  Babies are measured from crown or top of the head to the rump or bottom until about 20 weeks. Thereafter, they are measured from head to toe. This is because baby’s legs are curled up against their torso during the first half of pregnancy and very hard to measure.


This is a good time to start doing your Kegel exercise and other pelvic floor exercises. Your doctor can provide you with instructions for doing these exercises or you can refer to our section on pregnancy fitness to read about them.

The advantage of doing these exercises is that they prepare you for labour and birth. By toning up your pelvic floor muscles you will have more control over them. This will make it easier for you to deliver your baby when the time comes. These exercises also reduce your chances of having urinary incontinence post delivery.


1) How much weight should I have gained during the first trimester?

Most women gain 0.5-2.5 kg during the first trimester. However, if you are overweight, you will not want to gain more than 1 kg during the first trimester. However, nausea and loss of appetite during this time can cause you to lose weight instead of gaining. There is no need to worry as you will make up for this loss in the upcoming months. But if you continue to lose weight, you will need to see your doctor.
