First signs of pregnancy: week 5 of being pregnant - You will be able to take a pregnancy test this week.
This week you will be able to take a pregnancy test. You may know you are pregnant if you have done an early test, but will probably not be experiencing morning sickness yet. However you may notice other signs of pregnancy such as changes to your sense of smell. A plug of mucus has sealed your cervix.
By week five your baby's brain and the rest of the nervous system have started to develop. Your baby is gently floating in amniotic fluid. The nose, eyes and hands are forming and basic hand 'plates' are present. The heart is now beating strongly at twice your own rate. Blood vessels have formed and a tiny umbilical cord has connected itself to the rapidly developing placenta. Your baby measures around the length of a grain of rice.
