Parentree-editors 2008-10-29 00:24:39

You are 11 weeks pregnant or in your 12th week of pregnancy (counting from the first day of your Last Menstrual Period).

Keep in mind that this information is approximate. Each pregnancy is different and growth rates vary.  For variations and details, please talk to your doctor.

What’s happening to the baby?

  • This is a time when most of the vital organs are functioning.
  • The baby’s kidney is able to process the amniotic fluid that the baby drinks, and converts it into urine that flows back to the amniotic fluid.
  • The liver is functioning and can cleanse the baby’s blood and store and distribute nutrients.
  • The pancreas has started producing insulin for regulating the sugar levels in the baby’s blood.
  • The baby’s vocal chords are beginning to form. But your baby cannot make a sound until after birth because his windpipe is full of amniotic fluid rather than air.
  • The intestines have retreated into the abdomen instead of bulging out into the umbilical chord.
  • The brain’s complex structure of nerves is also being fine-tuned rapidly.
  • Hair, fingernails and toenails start arriving.
  • Your baby is about 5 centimetres long (Crown to rump length) and weighs about 8 grams.

What’s happening to mom?

  • As your first trimester is about to end (end of week 13), like many expecting parents you may be getting ready to share the news.
  • To prepare for the baby’s rapid growth, your placenta is busy at work expanding the number and size of the blood vessels for nourishing the baby. This means that you will start to gain weight.  10-14 kilograms is the recommended weight gain during pregnancy for Indian mothers. Remember, the extra energy that is required is only 300 kcal/day and any consumption above this will only add empty calories and weight to the mother.   The usual Indian advice is to eat for you and for the little growing baby and not necessarily for two adults.  Focus on nutrition and not the quantity of food.
  • In your dating scan you may have found out that you have twins or multiples. Read Parentree's article on Twins (or multiples).

Checklist for mom

  • Read Parentree's article about the importance of prenatal tests
  • If you have not already, talk to your doctor and schedule the Maternal Serum Marker test or AFP that all women need to take. This is a blood test that is taken between the 15th to 18th weeks and screens for Down syndrome or other birth defects. If the test shows abnormal results, then it does not mean that the baby has birth defects. It just requires further detailed diagnostic tests like amniocentesis
  • If you are above 35, and have a history of birth defects in your family, then your doctor might want you to take the amniocentesis test  (taken between 15th – 18th weeks) which is the definitive diagnosis for Down syndrome and other birth defects. In this case, your doctor might not wait for the results of the AFP test. Discuss this with your doctor.
  • If you have not already, read up about common pregnancy conditions (In Parentree's collection of pregnancy articles) to help you decide when to call the doctor.
  • If you have not already, ask your doctor for what medicines are safe to take for common problems (headache, fever, cold etc.) during pregnancy.
  • Your baby is poised for rapid growth and you need to continue eating healthy and paying attention to your diet. Refresh on nutrition and food during pregnancy.
  • Between weeks 11 - 13, you will have a doctor's visit for a comprehensive ultrasound scan to confirm the due date and to check for twins and the position of the baby in the uterus. This is also called the "dating scan".
