Your baby is looking more like a newborn. With every ounce of weight gained, their skin becomes less wrinkled. Their skin is getting pinker too, as every growing fetus's skin first does, regardless of their final skin tone, thanks to the capillaries (small blood vessels) forming under their skin; Blood vessels will begin developing in your baby's lungs this week, as well.

Speaking of lungs, your little one's beginning to produce lung surfactant, which is a combination of phospholipids and proteins, to coat the alveoli (the air sacs by which oxygen comes into the body) and prevent them from sticking together when your baby exhales. Their little nose and nostrils are beginning to work as well, preparing for that first, big breath of air.

This week, your baby can also sense which way is up and which way is down, respond to your voice, and startle at loud noises. Your baby's been busy!

By week 25, your uterus is about the size of a bowling ball; so your body is pure, unnatural magic if you're still wearing pre-pregnancy clothing. You may feel hotter - sweatier - than normal, due to your body’s increased blood flow. Dress in breathable fabrics to help wick off any excess moisture from your body. The same advice can apply during winter months, though you might decide on wearing a few extra layers of breathable clothing whenever you go out. And make sure you’re drinking enough water to avoid dehydration and combat any swelling.

Drinking extra water this week will also help you with another complication sometimes caused by your body's extra blood flow during pregnancy. Hemorrhoids, a type of varicose vein, are quite common during pregnancy and may even cause rectal bleeding. Hemorrhoids are very painful, and constipation (another joyous symptom of pregnancy) can make them worse. Drinking plenty of water and taking more fiber may also help.

You may experience some tingling, burning, numbness, or pain in your wrists around week 25, which could be carpal tunnel syndrome. Many women develop carpal tunnel syndrome during pregnancy if their carpal tunnel, a narrow, rigid passageway of ligament and bones, located in the wrist, becomes markedly swollen. When this happens, it presses on the median nerve, which controls sensations running from your forearms, down to your wrists, then to your fingers and thumbs. This may result in pain, weakness, or numbness in the hands and wrists, though sometimes it might radiate up the arms. Luckily, this usually subsides after pregnancy. In the meantime, wearing a wrist splint (found online and at most drugstores) may reduce discomfort.

Your glucose screening test should happen sometime between weeks 24 and 28 of your pregnancy. If you haven't been tested for gestational diabetes already, you need to make sure this test is scheduled soon. Don't stress over it, as this test is quite easy to take. You'll be told by your doctor to avoid food for a set amount of time and given a sugary type of solution. You'll drink the solution at the end of your fast and then, a little later, your blood is drawn to see how well your body processed the sugar. If your test confirms gestational diabetes, you may have to monitor or manage your sugar levels by using a glucometer to prick your finger for daily testing.
