11 Weeks Pregnant

Length of baby: 4cm (40mm)
Weight of baby: 7g (0.007kg)
At week 11, your baby’s head is the same size as the rest of it’s body at a ratio of 1:1.


As you know, with a little one in the picture, life for you and your hubby will change forever. Not that it is a bad thing! Because pregnancy has been on both you and your hubby’s mind since you found out that you were pregnant, this week is the time to take some time off just for the two of you. 

At week 11, you may start thinking and planning for a babymoon. Take off somewhere and enjoy each other’s company. 

Well if you don’t plan to get away, perhaps a staycation would work as well. Whatever your choice, spend sufficient time together because soon it will not just be you two lovebirds anymore.



How big is baby at 11 weeks? Your 11 week old baby is the size of a prune, which is about 40mm (4.0cm) big. The current weight of your baby is about 7grams (0.007kg).

Weird fact: The current head to body ratio is about 1:1.



You are still in your first trimester, so you do not need to gain much weight. By the end of the first trimester (week 12), you should be expected to gain anywhere between 0.5kg to 2kg. 



You are still in the middle of probably the worse stage of pregnancy due to the raging pregnancy hormones. Think positive because we promise you that it will only get better from here on. 

Being 11 weeks pregnant, here are some signs and symptom that your body might be experiencing:

  • Morning Sickness. Yes you can’t seem to get a break from the nausea, can you? Hopefully by now you would have found something (food) that can alleviate your nausea each time it strikes. If you haven’t had much appetite or if you haven’t put on any weight, your appetite will soon return and your weight will also increase subsequently. 
  • Fatigue. As your baby undergoes a growth spurt, your body is exhausting all energy and doing all it can to nuture it. 
  • Constipation. Due to your raging hormones, you might be having problems doing your number 2. Try to eat high fibre foods and drink lots of water.
  • Vaginal discharge. Due to the increase in estrogen levels, your body produces a clear, odourless discharge. This can be expected throughout your pregnancy. However if it is coloured (yellowish or greenish) and has a foul odour, call your doctor as you may have an infection that requires treatment.
  • Gas. Throughout your pregnancy, you will be experience tummy troubles. To alleviate the troubles, avoid gaseous carbonated drinks or foods that can cause gas such as beans and fried food.
  • Leg cramps. You will find that you have tight painful muscles all of a sudden. Stretch your legs throughout the day and remain active. Also ensure that you have enough potassium and magnesium in your diet.


At this stage you will find your usual clothing starting to get tight. Wear looser clothing to feel more comfortable.



You are now starting to have a tiny baby bump, though people around you might still not be able to tell. Wear loose clothing as you might find your usual wear starting to get tight.

What you will also notice is your breasts becoming noticeably bigger (something your husband might appreciate *wink*).

Even though you are only in the first trimester, your body is preparing the breast to breast feed the baby upon his or her arrival. 

The risk of miscarriage at this stage is at three percent, and the number will dip in the weeks to come.



You won’t feel it, but your baby is moving gracefully inside your womb. The tiny movements of kicking and stretching looks like water ballet. The movements will become more frequent as the body grows and develops (and that is also how you will feel the kicking in the weeks to come).

The diaphragm is also now formed, so the little one might start to get hiccups.

Your baby’s hands will soon open and close into fists, and tiny tooth buds, nail beds and hair follicles are beginning to form.

Some of the bones are now starting to harden, and he or she now also has skin that is see-through, but will soon turn opaque.



You will be going for your next prenatal appointment the following week at week 12. During this appointment, your baby will be screened for abnormalities, such as Down’s Syndrome.  

All expectant mothers have a 2% risk of delivering a baby with major physical or mental handicap. The most common is Down’s Syndrome, which occurs in about 1 out of 700 babies born.

You will undergo the combined first trimester screening test. For the first trimester screening test, you will undergo a blood test that looks for hormonal changes that can suggest a problem with the baby’s chromosomes.

More specifically it will measure the levels of two pregnancy hormones PAPP-A (pregnancy associated plasma protein A) and free beta-hCG (free beta-human chorionic gonadotropin). 

You will also undergo an ultrasound scan that measures the thickness of the fluid behind the baby’s neck, called the nuchal translucency (which is often bigger for babies with down’s syndrome). If the results show an increased risk, you can choose to go for a diagnostic test.

Diagnostic test (which is invasive) is the only sure way to know if your baby has Down’s Syndrome, however, this increases the risk of a miscarriage. As such, it is only offered to pregnant women whose results show a high risk.

The diagnostic test is required should you have a high risk which are Chorionic Villus Sampling and Amniocentesis.



Reminders for the week:

  • Play your babymoon or staycation with your husband
  • Start looking for maternity clothings, maternity underwears and maternity bras
