Your baby now measures about 2.5 inches (6.5 cm) from crown to rump and is about to start growing fast. Her internal organs are maturing. Baby’s movements are less jerky, and she can bend and twist all her joints. Eyebrows are starting to appear, and hair is starting to grow on the head. You can listen to your baby’s heart by holding an ultrasound instrument against your belly.
In preparation for life outside the uterus, your baby is now practicing breathing in and out, and filling her lungs with amniotic fluid. However, in her water-filled world your baby isn’t using her lungs to take in oxygen. Your baby gets oxygen directly from mom’s blood via the umbilical cord and placenta.
The placenta provides all the nutrients your baby needs and hormones that are important for the pregnancy.
You’re now into the second-third of your pregnancy—the second trimester—and you should be feeling less tired than you did at the start. You might even be feeling really great—if so, that’s fantastic! Many women consider the second trimester to be the very best part of pregnancy.
Your pregnancy will probably to start to show from around this week when you’re naked or wearing tight clothes. That said, all pregnancies are different. Some women find they’ve developed a belly bump by this point while it may be a bit longer before your tummy starts to bulge. If you’ve had a baby before, it’s possible that your belly is bigger now than it was in previous pregnancies—that’s entirely normal.
During this time, many mothers-to-be start feeling great. Their nausea subsides which is, of course, great for you too.
Do you enjoy exercising? Perhaps you could work out together. Not only is exercise good for both of you, it also gives you the perfect opportunity to talk about all the things that are happening in your lives at the moment.
