You are unique, your baby will be unique, and your pregnancy stages will also be totally individual. So never worry if your experience varies from the lists, guidelines and pregnancy advice you will find offered to you.

That said, if this is your first pregnancy it can be very helpful to be aware of the general course of typical pregnancy stages. Some mums-to-be suspect its going to be a less than happy nine months as they get larger and lifestyle changes loom. But be reassured, for most women this is a very exciting time.

So what can you expect? During those nine months there will be huge changes at each pregnancy stage for the baby in your womb and in your own body.

The growth of the foetus

Its miraculous: that tiny speck of an egg once fertilised grows through extraordinary stages into an amazing body that draws all her sustenance from you, until she can survive in the big world as an independent person. Many pregnant mums love to follow her progress. Knowing her size, when her heart starts pumping, fingernails grow, brain is formed its endlessly fascinating. There are lots of books and websites that help you chart her growth week by week through all stages of pregnancy.

Body bloom

And how about you? Amongst the pregnancy advice from friends and family you may have heard some of the tales youll be blooming, youll be sick all through, youll be eating seashells, your partner will adore/hate your changing shape, your love life will be sizzling/failing. Remember, youre unique. But here are some of the common changes many experience in the first, second and third trimesters.

- Most women find their boobs grow bigger. This is caused by release of hormones and it may continue until delivery.

- Increased hormones during pregnancy often lead to hair being more thick and glossy in the second and third trimester pregnancy, while nails are often stronger and can be grown longer. Others find their hair is more oily: use a gentle shampoo more often.

- Skin may become dry or spotty, in which case use chemical-free wash products; and if you develop stretch marks, use stretch mark cream and a good maternity bra.

- Gum disease is more common, so make friends with your dentist. NHS dental care is free during pregnancy and for the next year.

- Your body is working hard growing that baby, so you may find you get more tired than usual. But some mums-to-be feel a surge of energy, and linked to that famous nesting instinct, many wanting to decorate the house or at least the nursery. If you are tired, rest when you can. If you are spring cleaning, be sensible dont overdo it, and no climbing ladders!

- Eat healthily but dont eat for two; avoid alcohol and smoking; take moderate exercise throughout pregnancy; drink plenty of water; wear suitable shoes to look after your feet.
