Week 3 & 4
When the egg is fertilised it travels along the fallopian tube and embeds itself in the wall of the womb (uterus).
It starts to produce a hormone called ‘human chorionic gonadotrophin’ which stops you having a period and shows in your urine - this is what home pregnancy testing kits can detect when you miss your first period.
The first trimester
The first trimester, or first three months, is very important in your baby’s development as this is when the main structure of the baby’s body and organs are formed. Be careful of any drugs or medications - they could be harmful. Read the packaging very carefully and check with your doctor or pharmacist.
It’s best to avoid alcohol, too, in the first trimester. Check the current guidelines on alcohol during pregnancy.
Think about eating healthily
Pregnancy is a time to think carefully about what you are eating and drinking. Choosing organic foods can help you to plan a healthy diet without worrying about pesticide residues or artificial additives – and many people agree that organic foods taste better too.
