Your baby's lungs will grow extensively this week, even though he or she is still fed oxygen through the placenta in the womb.
The timing of this is Nature's way of ensuring that the baby can breathe if it is born premature.
Changes To Your Body At this point your baby requires many nutrients.
That's why doctors sometimes prescribe iron 30 mg supplements during the second half of pregnancy, in addition to your prenatal vitamins.
Contact your doctor right away if you suffer from fatigue, weakness, shortness of breath or dizziness as those are symptoms of iron deficiency.
Lifestyle Considerations You are getting larger, your feet may become a concern.
If you have not done so already put away any high heeled shoes for now and shop for a sensible pair of running shoes that can support your arches properly while you support the extra baby weight.
Don't be surprised too if your foot size increases by a half to a whole size.

Chat with your baby whenever you can as he or she can now recognize your voice.
