Your growing baby is about seven ounces (almost 200 grams) in weight now and is around five and half inches (14 centimeters) long.iii

What can you expect in Week 18 of pregnancy?

Some moms-to-be may get sudden nosebleeds at this pregnancy stageiv, due to increased blood flow during pregnancy. Avoid nosebleeds and enjoy your pregnancy with these tips:

  • Stay hydrated. Drinking more water can prevent your nose membranes from getting dry, which makes it easier for the delicate vessels in the nose to break and bleed.
  • Stay away from environmental irritants such as smoke.

What can I do to support my pregnancy in week 18?

By continuing to eat more calcium-rich foods this week, you’ll be helping your developing baby’s bones grow strongv. Foods that contain DHAvi remain important to support your little one’s  brain development.

Remember that from healthy brain growth stems good emotional development, as the brain is the center for emotions and their regulation, alongside its cognitive functions, such as reasoning, problem solving, and memory.

This applies to you too, mom-to-be. When you are stressed or anxious, your brain signals your body to release stress hormones such as cortisol.vii If the levels of these ‘stress hormones’ are consistently high, it could have negative health effects on your developing baby, according to prenatal health experts.viii

If you’re overwhelmed with having to deal with new symptoms and your changing body, talk to your doctor, a friend, your partner, or a family member about how you feel to get some support.

You could also try relaxation techniques such as controlled breathing, meditation, or simply engaging in activities that you know help you relax.
