Your baby measures about 2.2 inches (5.5 cm) from crown to rump and weighs about 0.5 to 0.7 ounces (14 to 20 gm). The neck is already strong enough to allow the baby to move her head.
Research indicates that your baby will start to hear sounds now. Of course, the ears aren’t fully developed until week 24, but it's believed that babies ““hear” sounds through sensory receptors in the skin that pick-up vibrations. Your baby will recognize your voices when she is born.
Your placenta is about the size of a fist now, and you may be able to feel the upper part of your uterus (the fundus) just above your pubic bone.
Some women continue to experience nausea throughout their entire pregnancy, but for the majority the nausea has subsided completely by now. Your uterus is now growing at a regular and noticeable pace. The risk of miscarriage has fallen by around 65 percent by week 13, and many couples allow themselves a sigh of relief at this point.
How does your tummy feel? When you’re pregnant, your intestines move more slowly, so there’s a chance you feel constipated. A kiwi fruit every morning, or some chia seeds or linseeds sprinkled on your morning yoghurt could help to get things moving. Also remember to move around and drink plenty of fluids! Problems with your rectum such as hemorrhoids, itching or fissures are common too. Speak with your health care provider or pharmacist to find out how you can relieve the symptoms.
It is nothing unusual to have an ultrasound examination during pregnancy. The technician will look at all the major organs and structures to see how your baby is developing and to locate the placenta. You can also see your baby for the first time—this can be an exciting experience! Your estimated due date (+/- 2 weeks) is determined at this point.
If you need to update your estimated due date in the app, do so under Settings > My pregnancy> Estimated Due Date.
