You are now 13 weeks pregnant which is the beginning of week 14. Your baby is now 9 cm long (or 3.6 inches) and weighs approximately 50 grams (or 1.75 ounces). Many women notice a renewed burst of energy by this stage, but may feel concerned because they do not experience as many obvious signs of pregnancy (and it is too early to feel the reassuring movements of their baby yet). You may need to loosen the clothing around your waistline now, but at this stage many women say they feel they just look 'fat', rather than pregnant! From here on in, your baby will grow quite rapidly and in the coming weeks your belly will quickly 'pop out'!
Your baby's body now grows more rapidly than their head. If you see your caregiver, they should definitely be able to feel the top of your uterus (called the 'fundus'), byfeeling your belly. If they use a special Doppler machine, they should also be able to detect your baby's heartbeat so you can hear it!

The placenta is now producing most of the pregnancy hormones, particularly progesterone. Progesterone is responsible for many of the physical changes during middle pregnancy, such as increases in skin pigmentation, lowering the blood pressure, increasing constipation and possibly causing bleeding gums or nosebleeds.
Your baby now has a gag reflex and their nose and nasal passages are fully developed.
