First trimester weeks 7-8

Your pregnancy: seven to eight weeks

The first weeks of your pregnancy are a vital time as your pregnancy gets established. While you get used to being pregnant, your body is busy building a baby!

If you have just found out you’re pregnant and have drunk alcohol or smoked, try not to worry. You can take steps now to look after yourself and your baby by having a healthy lifestyle.

Seven to eight weeks pregnant: your baby

Your baby's tiny heart is already beating and her head is taking shape. Organs are forming, including her kidneys, lungs and liver. By eight weeks she'll be around the size of a kidney bean.

Her limbs are continuing to develop. Your baby's arms will take shape faster than her legs. Her inner ears are starting to form.

The tube that connects the spine and brain, called the 'neural tube', closes up.

By eight weeks, your baby is called a 'fetus' rather than an embryo.

Seven to eight weeks pregnant: you

Although there's not much to show anyone else that you're pregnant yet, your body is going through some major changes.

Whats happening to your body

Your body is preparing itself to support your baby.

  • The volume of blood that is being pumped through your heart increases, making your heart rate go up. This will make you feel more tired than usual.
  • Hormonal changes can make you feel sick or be sick. Although this is called morning sickness, it can happen at any time of the day.
  • You may notice that you need to wee more often. This often starts in early pregnancy thanks to hormones and continues as your growing womb presses on your bladder.
  • You might feel thirstier than usual in early pregnancy as the volume of blood in your body increases.

How you may feel

  • Your baby is growing at an amazing rate. Right now, you might feel as though you can't possibly feel this tired for another seven months! Don’t worry, the extreme tiredness goes away in the second trimester. Even if you feel exhausted, try to stay active or doing your normal amount of exercise. It might actually increase your energy levels as well as helping you sleep.
  • It can feel like a long wait in the early days of pregnancy between telling your doctor about your positive pregnancy test and having your first antenatal appointment. You may feel a bit unsure about things. Talk to your doctor if you have concerns about your health or your baby's. Have a look at the box below to find out what you can do to look after your health and your baby’s health before your antenatal care begins.

Seven to eight weeks pregnant: things to think about

Your antenatal care

If you haven’t done it already, make an appointment to see your doctor, or arrange to see a midwife. You can find a midwife by contacting your local doctor's surgery, health centre or children's centre. Many hospitals now have a self-referral facility for antenatal care. You can contact the hospital directly or fill out an online form to refer yourself to local maternity services.

It's important to make this appointment so your antenatal care can be sorted out.

Make sure you go to all the appointments during your pregnancy – that way queries or concerns will be dealt with as they arise.  It is also a good time to ask about the government Healthy Start programme. You might be eligible for free pregnancy vitamin supplements and food vouchers.

Tell your doctor or midwife if you are being treated for any health conditions, such as diabetes, high blood pressure or thyroid problems. You should also let them know if you had complications such as pre-eclampsia in a previous pregnancy.

Let them know if you have are on any medication for mental health issues or if you had any mental health problems such as depression or anxiety in previous pregnancies. This helps to make sure that you get the right support at the right time if it happens again.

At or after your first appointment, you should be given a date for your booking appointment, which will be between weeks eight and 12. At this appointment, you'll be asked lots of questions so the midwife can make sure you have the best possible care during your pregnancy.

Pregnancy and work

If you're working and you think your job could be a risk to your health in pregnancy, tell your employer in confidence that you're pregnant. Once you have told your employer in writing they must carry out a risk assessment and make any necessary changes to protect your health and the health of your baby.

Things that could cause a risk might include:

  • heavy lifting or carrying
  • standing or sitting for long periods without adequate breaks
  • being exposed to toxic substances
  • long working hours.

If there are risks, your boss should take reasonable steps to remove them. This could be by offering you different work or changing your hours, for example.

If your employer can't remove any risks, they should suspend you on full pay. You can read more about your rights at work as a pregnant woman on this goverment website.

Telling people about your pregnancy

Other than telling work if you think your job poses a risk, many women wait until they’re three months pregnant to tell people. This is because after three months the risk of having a miscarriage goes down. If you do have a miscarriage, though, you are likely to need the support of close family and friends so you could consider telling just a few people before the end of the first three months.
