Pregnancy by Month: Month 4

The fourth month of pregnancy includes weeks 13-16.  It is the first month of your second trimester.  For many women, the second trimester is the most comfortable.  Often times the morning sickness and fatigue that plagued you in your first trimester have worm off and you're not yet big enough to feel the discomfort of third trimester.  You may notice increased energy and by now may have the beginnings of a baby bump.

Week 13

for Baby:

Until now, your baby's head has been much larger than the rest of the body.  But now is when your baby's body will start to grow and catch up to the proportions of the head.  Although you can't feel it yet, baby is moving around and flexing joints.

for Mom:

Your risk of miscarriage is significantly reduced as you enter into these weeks of pregnancy.  You may also notice your symptoms from the first trimester begin to subside.  Take advantage of the boost in energy by preparing for the arrival of your little one. You can sign up for childbirth or child care classes, schedule a hospital tour, or start planning your nursery.

Week 14

for Baby:

Now your baby's well-defined face can make expressions.  He or she may be squinting or frowning.  Hair may begin growing on the head and face.  Your baby already has their unique set of fingerprints.  Baby now responds to outside stimuli. For example, if your belly is poked, baby will try to wiggle away. If you are having a girl, she has already developed eggs inside of her ovaries and a boy will be developing his prostate gland.  

for Mom: 

By now, you may very well be showing a baby bump.  It's a good time to invest in a few maternity wardrobe staples.  If you've had a previous pregnancy, you are likely to start showing sooner and it's not uncommon to be able to feel the baby's first movements, or flutters, at this time.  Some women begin to experience constipation at this time.  Try to up your fiber intake and not strain while pooping as that can cause the dreaded hemorrhoids to appear.

Week 15

for Baby:

A very fine coat of hair called lanugo, is covering your baby's body.  This hair protects the baby's body from being constantly exposed to the amniotic fluid and will typically shed during birth.  Baby's bones are starting to get harder and your little one may even begin sucking their thumb.

for Mom: 

The blood in your body is continuing to increase.  It is important to make sure you get enough iron in order to avoid becoming anemic.  Your mucous membranes may begin to swell causing stuffy nose or nosebleeds.  If sleeping is beginning to become uncomfortable, use pillows to support your legs, back and hips.  Sometime within the next few weeks your doctor will perform a blood test to help screen for Down Syndrome.

Week 16

for Baby:

Baby's skeletal system is developing as the bones become stronger.  Baby's limbs are much more developed as the arms and legs are longer, stronger and more controlled in movement.  Baby is approximately 4.6 inches long.

for Mom:

You may experience round ligament pain, or RLP, which is caused by the round ligaments stretching and thickening to support your growing uterus.  Often RLP is noticeable when you move to quickly or sneeze.  If you have not already, you may feel baby's movements, called quickening, for the first time within the next couple weeks.  Many women compare it to a fluttering sensation and typically it is first felt between weeks 16 and 22.
