Pregnancy length is worked out from the date of your last period so by the time your period is missed you are already one month pregnant. You may notice some changes in your body such as breast tenderness. During the first few months your baby grows faster than at any other time in pregnancy. You can find out how far along your pregnancy is and what is happening in your pregnancy week by week by using a pregnancy calculator
Towards the middle of your first trimester you will experience a surge in hormones which can cause symptoms such as morning sickness, tiredness and heartburn. Your baby now measures around 5 cm and their brain, spine and nerves are developing fast.
Towards the end of your first trimester your baby measures around 6 cm. Their digestive system is developing and facial features can be seen in an ultrasound scan. Your baby has fully formed fingers and toes and begins to kick. They can bend their arms and legs and their heart is beating around twice the speed of yours.
You will probably have an ultrasound scan around 12 weeks and you will see that your baby now has fully formed arms, legs, fingers and toes. They now have facial features and their digestive system is forming. Their heart will be beating quite fast and they can use their arms and legs to stretch and kick. They now measure approximately 6 cm long
Your early pregnancy symptoms may start to fade due to changes in your hormone production. As muscles and ligaments in your pelvis stretch to accommodate your growing baby, you may get some aches and pains. A pregnancy calculator is a useful tool to find out about changes in your body and how your baby is growing.
Your baby will soon be able to hear your voice. During this trimester you will begin to feel your baby move and by 21 weeks will have short periods of activity while they explore their surroundings.
As they continue to grow their eyes and ears will fully form and they may begin to respond to your voice.
As you enter the third trimester your baby has fully developed lungs and may react to loud noises. They may begin to suck their thumb and will have longer periods of activity. Movements will become smaller as they begin to run out of space. Their bones will harden from cartilage to bone and they will begin to put on fat.
The last trimester can feel like the longest as you wait to meet your baby. He or she will soon move into position for birth. Their bones are hardening and their lungs are now fully formed. Your bump will grow larger as your baby continues to put on weight and grow. Their movements will start to become smaller as space becomes restricted. Use a pregnancy calculator to find out exactly how your baby is developing during this time.
