Your baby's blood vessels are visible through his thin skin, and there's no baby fat yet to plump him up.
Avoid lying flat on your back now. Your growing uterus compresses major blood vessels, decreasing blood flow to your baby.
Keep moving: Standing still – while doing yoga poses, for example – can lower your blood pressure and make you dizzy.
You're in your fourth month!
Dem bones
Your baby's skeleton is changing from soft cartilage to bone.
Lifeline
The umbilical cord – her lifeline to the placenta – is growing stronger and thicker.
No sweat
Sweat glands are starting to develop.
Unsteadiness
Starting to feel a bit off balance? As your belly grows, your center of gravity changes, so you may begin to occasionally feel a little unsteady on your feet. Try to avoid situations with a high risk of falling. Wear low-heeled shoes to reduce your risk of taking a tumble; trauma to your abdomen could be dangerous for you and your baby.
Dry eyes
You may also notice your eyes becoming drier. Using over-the-counter lubricating drops may help. If your contact lenses become uncomfortable, try wearing them for shorter stretches of time. If you still have discomfort, switch to glasses until after you give birth.
