The baby is fully formed and even has tiny unique fingerprints. The sex organs are continuing to develop, and if you could see inside your womb it would be just possible to see whether the baby is a boy or girl (although ultrasound scans cannot tell sex accurately at this stage).
Your pregnancy is now officially in the second trimester, the middle part of your pregnancy. Your midwife will be able to feel the top of your growing womb. With your pregnancy at 14 weeks your stomach will be getting rounder, and your bump might be showing slightly. Start getting into the habit of moisturising your skin well - although it's not possible to prevent stretch marks, which usually appear around the sixth or seventh month of pregnancy, moisturising may increase the suppleness of the skin, and make them less noticeable. Dads can help too, by gently rubbing in lotions and creams.
If you had 'morning sickness' during the first three months, it's probably wearing off by now. Your appetite should be coming back too. The Recommend Daily Allowance (RDA) for protein in the last two trimesters is for an additional 5g per day, equivalent to a pint of semi-skimmed milk. Drink a glass of fruit juice each day to meet your increased requirement for vitamin C. You can also stop taking folic acid supplements, because your baby's nervous system is well developed.
