You may begin to feel the baby move around this point. Many women don’t feel this movement for a few weeks more – you’re more likely to feel it early if you are multipara (ie, this is not your first baby) or if you are very thin. Generally you will feel the baby move about one month earlier than you did in a previous pregnancy, mainly because you know what you are feeling. It is not uncommon for first time mothers to not recognize fetal movements until 22-24 weeks.
Your baby will react if your stomach is poked or pressed. The baby is also becoming sensitive to light outside the womb, but unfortunately that doesn’t mean that it will sleep or rest at the same time you do. Later on in your pregnancy, night time movements can make it difficult for mums to get a good night’s sleep.
Your baby’s nails are well formed, and by the time he or she is born, they may need their nails cut right away. The ears have also moved from the neck to the head.
Your baby is emptying his or her bladder every 40-45 minutes. The limb movements are becoming more coordinated. Your baby is about 3 ounces (85 grams) and 16 cm. It’s still a bit early for an ultrasound to tell you the gender for certain.
Between 16 and 20 weeks you may also be offered amniocentesis. An amniocentesis test uses a sample of the amniotic fluid surround your baby to find out if it has serious genetic conditions such as Down’s syndrome. The test is only recommended if you are at risk of having a baby with these conditions, because there is a 1% chance of the test causing miscarriage. Risk would be measured partly by your age and partly by family medical history.
From the early stages of pregnancy, your womb presses on your bladder, making you need to urinate more frequently. But if you’re finding it painful to pass urine, there’s blood in your urine, or you feel generally feverish and unwell, you may have a urinary infection called cystitis. It’s particularly common in pregnancy because it’s harder for your bladder to empty fully and your bladder lining becomes softer. If you think you have cystitis, visit your GP, or ask your pharmacist for over-the-counter remedies that are suitable for use during pregnancy.
