Pregnancy: Week 18

You may be experiencing some lower back pain around week 18 and on, but one thing that can distract you from this new development is another incredible development: you may begin feeling your baby move around inside your belly.

What to Expect with Physiological Development

At this moment, your baby is approximately five and a half inches long, being measured from crown to rump, and weighs about 5 ounces. If you want to put this into terms you may easily understand, is that it’s about the same size as that boneless chicken breast you had for dinner recently.

Your baby’s nervous system is maturing at quite a good pace now. Nerves are beginning to form more complex connections and your baby is beginning to develop the sense of touch, taste, smell, sight, and hearing.

Your 18 Week Ultrasound

During a week 18 ultrasound, many parents begin to notice that their baby is moving around much more fervently, especially in response to certain sounds, voices, songs you may be singing, and more. If you’ve been in the habit of singing certain songs to your baby, especially those you plan to sing to her after she’s born, she may respond to that now, even during the ultrasound.

You will likely also see your baby’s movements seem to be more exploratory, which is normal at this stage.

Changes in You

You can feel your uterus approximately 1 ½ inches below your belly button at this point in your pregnancy. Your uterus is actually about the size of a cantaloupe. This usually leads to the beginning stages of some back pain.

This is due to a shift in gravity and your lower back is being pulled forward while your abdomen is being pushed out.

What You Should Be Doing

You can consider taking a nice, long, warm bath that can help alleviate a tremendous amount of that lower back pain. If the pain you feel is continually bothering you, let your doctor know about it.

Ending Week 18

Keep in mind that low blood pressure can accompany pregnancy. It’s a good idea to go slowly whenever you’re shifting from a lying down or seated position to standing. If you move too quickly, you could feel some dizziness and put yourself at risk of falling down.
