During 15 weeks pregnant, your baby is now 4 inches long and weighs about 2 ½ ounces which is about as big as an apple. Beginning this week, you, being a pregnant woman, are finally noticeable as your baby grows so fast every week. What a busy buddy at 15 weeks pregnant!

Your Baby’s Development this Week

General changes

Your baby is constantly moving inside you, however, you won’t still feel anything although you may sometimes feel your baby kick. Your baby’s movements will be felt more easily and more often later in the pregnancy. When you go for an ultrasound, you will be able to see your baby doing many facial expressions such frowning and grimacing.

He is also squinting, hiccupping and can also move his thumb into his mouth to suck. When your baby hiccups, there’s still no sound due to his trachea full of body fluid instead of air. His arms and legs are also continuing to grow longer and can move all of joints and limbs now. Your baby’s head has been the biggest body part. The fingernails and toenails are also lengthening, and his taste buds are beginning to form. Other things he is capable to do are sucking, gasping and swallowing.

External and internal changes

Your baby is becoming hairy! There are fine hairs covering his skin known as lanugo, which serves as a regulator for his body temperature, keeping your baby warm. However, the hairs will eventually shed before birth. There are also hairs starting to sprout on top of his head, but the color may change eventually. The hair on the eyebrows is also beginning to grow. While his eyelids are still closed, your baby can still sense the light. The nose and lips are also forming well.

Bones are also beginning to harden, including the bones on his ears, which is now also functioning. Your baby is now capable to hear sounds such as breathing and heartbeat, even the sounds outside like you people talking or music. This is also the reason why some of soon-to-become parents are playing soft music for their baby, helping them to calm as well as talking to them, which is also one of the steps for the baby’s brain training while inside the womb.

Gender chat

The much awaited news by your family and friends of whether your baby is a girl or boy has finally come. While being 15 weeks pregnant and if you go for an ultrasound, you may now know the gender of your baby! However, some doctors could not find it right away because of the constant changes in the positions of your baby. His genitals may be developed enough and visible to ultrasound.

Your Body Changes at 15 Weeks Pregnant

Mouth in particular

Your early pregnancy symptoms are now gone and you may be feeling more on your usual self. However, this 15th week, you may notice that little problems are occurring on your mouth area due to some pregnancy hormonal changes of course. When you look at your mouth in the mirror, you will see that you have red, swollen gums.

If you closely look, you will also see that there are small bumps forming on your gums and this are known as pregnancy tumor. Don’t panic! These are harmless and painless. If you see some on your gums, they will eventually disappear after you give birth.

You may also notice that they are sore, sensitive and bleeds while brushing teeth. Pregnancy hormones are affecting your gums and at this point, they triggering gingivitis or inflammation of the gums by making them react differently to the bacteria in plaque.

Breasts in detail

Your breasts’ milk glands are already busy producing milk. Looking at your nipples, you will see that it is wet on the tips in the morning. It is because your body is rehearsing colostrum production, which is a fluid rich in protein and it is good for your baby.

Tummy talk

You will also notice that you’re getting bigger but you’re still able to walk on your own. Your womb is also beginning to get bigger, out of your pelvis and due to that, many people will notice that you are pregnant. Finally, you can show off your baby bump now! Though, you are still adjusting to your sleeping and sitting positions.

This week, you will now feel Braxton-Hicks contractions, but not so intense. More like a practice contractions. You will feel tightening pain on your abdominal area or in your uterus. If you feel the contractions are coming at you regularly, you’re feeling uncomfortable pelvic pressure, or severe mucus/fluid discharge, consult your health care provider immediately.

Seeing your baby bump sticking out, you will notice that there is a dark line running down your bump. This line is known as lineanigra to doctors and it normally appears on pregnant women. It will eventually disappear after you delivered your baby. You may also feel slightly breathless, but this will get more annoying in the coming weeks of your pregnancy as your uterus pushes up against your diaphragm leaving little space for the lungs to expand.

What to Think and Do this Week

While your baby is getting bigger, you’ll find walking troublesome soon. But practice makes it perfect! You should now learn or adjust on walking in a new position. Not only on walking, you should now also learn to sleep on your side, sit or stand in a more comfortable position. Early practice will help you prepare for the coming troublesome changes on your pregnancy.

Now is also the best time for you to enter antenatal classes. This will help you learn more and get ready for the pregnancy labor and birth. You should plan to have completed the classes by 37 weeks. You also need to improve you abdominal and pelvic floor muscles. Make your abs stronger and pelvic floor now so that you will have an easier delivery and also reduce the danger of incontinence.

Though it is still too early to think and decide about the type of birth toy you want for your baby, take some time do some research and learn about these things. When you visit your health care provider, you can also ask for their recommendations. At the same time, take some information about taking the triple screen at 15 weeks pregnant, a blood test given for early detection of your baby's risk for birth defects including Down syndrome and spina bifida.
