Week 19 Pregnancy Symptoms

During week 19 of pregnancy, your body is adjusting to the new life it’s supporting. As your baby changes, you will too, and there are certain pregnancy symptoms you may experience at this time. Keep these week 19 pregnancy symptoms on your radar:

  • Sore back or sciatica can cause you pain at this stage. You’re growing rapidly and the extra weight and stretched muscles can hurt. Try yoga or Pilates to get movement into the area, and a heat pack or a support cushion on your chair.
  • You may get stretch marks as your tummy grows
  • Your sleep may be getting disturbed. A few basic changes can help.
  • You may get nasal congestion.
  • Yeast infections are a strong likelihood during pregnancy, so ask your doctor for any preferred treatments.


Being 19 weeks pregnant is an important time for you and your baby. Get advice on how to adjust to this new stage.

  • With the mid-pregnancy ultrasound coming up, you have the potential to learn your baby’s sex (or not). Decide if you want to know the sex of your baby before you head to the appointment.
  • If you haven’t already, now is a good time to find a pediatrician who can serve as your baby’s doctor once they make their way into the world.
  • Heartburn is one of the most unpleasant and regular symptoms you can experience when you’re pregnant. Learn what to eat to reduce the effects of heartburn.
