The Baby Inside You When You are 12 Weeks Pregnant

How is your baby doing when you are 12 weeks pregnant? At this stage, your baby is about the size of a lemon and is growing rapidly. His or her heart is now beating about 140 times per minute, and he or she can probably even hiccup! You may be starting to feel movement, though it may still be very subtle. All of his or her organs are present and functioning, and gender can usually be determined on an ultrasound. Read on to learn more about what to expect when you are 12 weeks pregnant.

What To Expect At 12 Weeks Pregnant?

You may begin to feel movement from your baby, called quickening, though it may feel like gas at first. This is a normal part of pregnancy and nothing to worry about.

You will likely have your second-trimester screening during this week or the next. This screening includes a blood test and an ultrasound. The purpose of this screening is to check for certain birth defects and chromosomal abnormalities.

If you have not already done so, you should start taking prenatal vitamins at this time. These vitamins contain folic acid, which helps prevent certain birth defects of the brain and spine.

Signs and Symptoms

Some of the signs and symptoms that you may experience include:

  • fatigue
  • nausea
  • breast tenderness
  • increased urination
  • mood swings

Your Baby at 12 Weeks

Your baby is the size of a plum at 12 weeks pregnant. All of their essential organs are formed and functioning, though they will continue to grow and develop throughout your pregnancy. Your baby’s heart beats approximately 150 times per minute, and they are able to make facial expressions. You may be able to feel your baby moving around this week, though it will likely feel like flutters or gas bubbles at first. If you have an ultrasound this week, you may be able to see your baby sucking their thumb!

What You Must do When You’re 12 Weeks Pregnant

You are in the second trimester of your pregnancy. This is a time when your baby is growing and developing rapidly. Here are some things that you should do during this time:

  3. Get plenty of rest. Pregnancy can be exhausting so make sure to get enough sleep each night. Consider taking naps during the day if possible.
  4. Exercise regularly. Exercising helps to keep your energy levels up and can help improve your mood during pregnancy. Just be sure to listen to your body and not overdo it.
  5. Stay hydrated by drinking plenty of fluids throughout the day (water is best).
  6. Avoid risky activities such as smoking, drinking alcohol, or using drugs as these can harm both you and your baby
