Pregnancy Week 12

Woman who is 12 weeks pregnant

Relax! Most women will be experiencing a decrease in morning sickness this week. Here is what else you can expect.

Pregnancy Week 12: What changes are occurring with your body?

Your uterus is continuing to grow, and your healthcare provider can now actually feel it in your lower abdomen. You may not need maternity clothes at this point, but you may have noticed that things are not fitting as well. If this is a subsequent pregnancy, you will most likely need maternity clothes sooner than a woman who has never been pregnant before.

You may have also noticed that your skin is changing, such as the darkening of the areola. Other changes you may have noticed include irregular dark patches on your face and neck. These are called chloasma or mask of pregnancy. These patches normally disappear or become lighter shortly after delivery.*

Pregnancy Week 12: What is happening with your baby?

This week your baby will begin to take on more of a normal appearance as the eyes move closer together and the ears move closer to their final position. The intestines have grown so fast that they actually extend into the umbilical cord, but they will begin to move back into the abdomen. The kidneys can now secrete urine, and the nervous system is continuing to mature. Your baby may have developed more complicated reflexes such as sucking.*

Pregnancy Week 12: How big is your baby?

Your baby is 3.15 inches (8 centimeters) long and weighs 1 ounce (about 28 grams) by the end of this week.*

Pregnancy Week 12: What should you plan for this week?

Now is a great time to really look at your diet and make sure both you and your baby are receiving all of the nutrients you need. It is important that you realize that just because you are pregnant, this does not give you a go ahead to eat all you want. Weight should be gained throughout your pregnancy.

You can avoid gaining excess weight by:

  • Avoiding fast food/junk foods
  • Avoiding late night snacks
  • Limiting fats and sweets

Pregnancy Week 12: Tips for making your pregnancy better

Many women benefit from Kegel exercises before, during, and after pregnancy. Kegel exercises are for strengthening the vaginal muscles. Pregnant women who perform these exercises find that it helps with birth and tones the muscles for after delivery.

Pregnancy Week 12: Tips for mom’s partner

Your partner’s body is going through many changes, and things that she once did easily may become more of a challenge. A good way to show her that you appreciate her and that you care is by rubbing her hands, feet, or back at the end of a long day. You can use her favorite fragrance of lotion or massage oil to make this time even more special.
