12 Weeks Pregnant: Baby Development, Symptoms & Signs


If you haven’t noticed, your baby’s major organs and important bodily systems are now completely developed! In case you haven’t already, your next prenatal exam will allow you to hear the heartbeat of your unborn child. Isn’t that exciting? 

At 12 weeks pregnant, you may notice that your bump has become a bit more prominent.

12 weeks pregnant: how much does my baby weigh? 

Your baby’s crown-to-rump length is now between 2 and 2¼ inches, which is around the size of a lime.

This is hard to imagine, particularly because you’re probably barely showing at this stage, but your kid has doubled the size by now.

The baby’s digestive system begins working

You and your baby are entering a new phase this week. Most of your baby’s systems are now completely developed when you are 12 weeks pregnant, but there’s still a lot of maturation to do before they’re ready to enter the world.

For the following 28 weeks, your foetus’ systems will continue to develop and the organs will begin to function. One of the first things your baby’s digestive system will need to do after delivery is to practise contraction motions, which will help drive food through the intestines.

Your baby’s bone marrow is hard at work producing white blood cells, which will one day help her fight illness when she’s out of your safe haven and in a regular playgroup. In addition, the pituitary gland at the base of the brain has begun producing the hormones that will allow her to have children in the next several decades.

Fetal heartbeat

A sound that will make your heart soar with excitement is likely to be heard during this month’s checkup for those who have not yet had the opportunity.

There are no longer any signs or symptoms of pregnancy

Your uterus, now the size of huge grapefruit, moves from the bottom of your pelvis to the front and centre of your abdomen when you are 12 weeks pregnant. 

It’s possible that the continual desire to urinate will be alleviated by this.

Early pregnancy symptoms including nausea, sensitive breasts, and nipples, food aversions, and exhaustion are also expected to fade as you approach the second trimester.

12 weeks pregnant: Your belly 

When you’re 12 weeks pregnant, your baby bump may become more visible to the outside world. It’s possible, though, that you won’t yet be able to tell that you’re pregnant by looking at your stomach. If anything, you may seem to have put on a few pounds around the middle, or you may not appear to have changed at all.

Regardless of how large, little, or invisible your 12 weeks pregnant belly is, remember that it is perfectly normal. The size and form of a pregnant woman’s baby bump may vary greatly based on her body type and whether this is her first or second pregnancy.

Please do not be concerned if your bump at 12 weeks does not resemble one of your pregnant buddies. You can’t go wrong with any bump. In the event that you haven’t started showing yet, don’t worry about it. Either way is okay. If you have any questions, don’t hesitate to contact your GP.

12 weeks pregnant: Advises

Get a flu vaccination!

It is advisable that all pregnant women be vaccinated against the flu. The danger of negative effects from vaccines isn’t increased if you’re pregnant, according to new research.

Embrace your loose style

Your GP doctor can feel the growth of your uterus in your abdomen, but there may not be a bump there to show for it to him or her. Shop for looser or flexible clothing, such empire-waist maxi dresses, drawstring trousers, and lightweight sweaters, until you’re ready for maternity attire.

Staying hydrated is essential

Your water bottle should be your best friend! You should drink an additional 8-ounce glass of water for every half-hour of physical exercise now since staying hydrated is more critical than ever.

Don’t be afraid to consume water instead of sports drinks whenever feasible. Increase your intake when it’s hot outside or you’re simply plain sweaty.

Be aware of what meals to avoid

You may come across soft cheeses manufactured with unpasteurized milk, which may contain listeria and other harmful viruses.

If you want to be safe, only eat pasteurised feta, Brie, Camembert, goat cheese, blue-veined cheeses, and queso fresco. To be on the safe side, always double-check the label.
