7 Weeks Pregnant
YOU
Most of the changes taking place in your body won't be obviously
noticeable: your body will now be producing more blood as the
placenta uses aroud 25% of the blood in your body, your cervical
mucous will form a plug at the opening of your cervix to protect
your baby from the outside world. This plug will stay in place
until your cervix begins to dilate ready for delivery, either late
in your pregnancy or during your labour.
However invisible, these changes are taking a toll on your body
and you are probably still feeling incredibly tired. Get your
partner to help out around the house where possible and forget
about all but the basic chores.
Sadly, around 25% of pregnancies will end in miscarriage, most commonly
between 6-8 weeks. Signs to watch for include vaginal
bleeding and cramping similar to period pains. Many women who
experience vaginal bleeding in early pregnancy go on to have a
healthy baby, but if you have any bleeding at all it's important to
let your GP or LMC know immediately.
YOUR BABY
Your baby now measures about 5-13mm in length from top to
bottom and weighs about 0.8 grams.
At this stage your baby has a shape similar to a sea horse, his
or her head is much bigger in proportion to the rest of the
body.
Your baby's heart is now beating at a rapid 150 beats per minute
(almost twice an adults heart rate) and has divided into right and
left chambers. Other areas that are developing include your baby's
digestive system, lungs, pituitary glands and muscle fibres.
Your baby's arms and legs are now starting to resembles paddles
while fingers and toes are forming. Baby's jaw, mouth, lips and
tongue are continuing to develop and grow and are also now
visible.
Although you won't be able to feel them for several weeks, your
baby is also beginning to make tiny movements.
If you have had fertility treatment, are unsure of your dates or
have a history of miscarriage you may have an ultrasound this week
to check on your baby's progress. This scan will confirm your due
date and whether you are carrying one or two (or more!) babies, and
you should also see your baby's heartbeat, a reassuring sign!
