Over the next few weeks, the embryo grows very quickly, and all the major systems of the body begin to develop. By the end of pregnancy week 5, the brain and spinal cord (the central nervous system) have begun to form. The heart divides into separate chambers and begins to beat.
Your period would be due about 2 weeks after ovulation. If you've conceived, this is the week when you'll miss your period. This is usually the time when women take a urine pregnancy test to confirm whether they're pregnant or just late. You can buy a test at your local pharmacy or supermarket, or get a test performed by your GP, practice nurse, or family planning clinic. If you're using an IUD (intrauterine device) for contraception and become pregnant, your doctor will check that your pregnancy is not ectopic (developing in the fallopian tubes). You may have the IUD removed, because it can cause miscarriage.
When you're pregnant, there are lots of foods that you're advised to avoid, including soft cheese, paté, and uncooked eggs. Ask your GP or midwife for more advice.
