12 Weeks Pregnant – What To Expect In Week 12

12 Weeks Pregnant - What To Expect In Week 12

You’re 12 weeks pregnant, which means you’re at the end of the first trimester!

Finally, you’re likely past the early pregnancy tiredness and morning sickness (or not far from it!).

Bring on some more energy and that famed pregnancy glow.

12 Weeks Pregnant – What To Expect In Week 12

You might rediscover your sex drive returns now you’re entering your second trimester.

Just bear in mind your cervix is quite sensitive during pregnancy.

It’s not unusual to see some spotting or even light bleeding after sex.

This happens because pregnancy hormones make the cervix softer and more likely to bleed.

It can be worrying to experience bleeding during pregnancy.

If you do have any spotting or bleeding make sure you speak to your care provider.

Don’t let this put you off having sex during pregnancy if you feel like it.

Just remember to ask your partner to go gently and try positions which reduce pressure on your cervix.

12 Weeks Pregnant Symptoms

While the extreme fatigue and nausea might shift, new symptoms take over.

Now you’re twelve weeks pregnant, your uterus has now grown above your pelvis.

This has taken some pressure off your bladder.

You should notice you don’t need to go to the toilet quite as often, and this will last until baby is quite a lot bigger.

However, your digestive system is going to get squished in the coming months.

So keep an eye out for signs of reflux or heartburn.

To reduce reflux during pregnancy you can try:

  • Eating small meals more frequently
  • Avoid acidic foods like tomatoes, citrus fruits, greasy food, coffee and spicy foods
  • Increase fluids, even things like smoothies, to ease symptoms
  • Don’t eat 3 hours before lying down in bed, elevate your head and lie on your left side.

Dizziness can be a problem too.

Your expanding uterus can put pressure on your blood vessels, and this can lead to you feeling dizzy.

In addition, over the next few months your blood pressure will begin to drop and you can feel dizzy quite frequently.

The best way to cope with dizziness when pregnant is to lie down, preferably on your side. Eat and drink regularly, to avoid low blood sugar which can also lead to feeling faint.

You might also notice you have more frequent headaches.

If you do, read about the five most common causes of headaches during pregnancy.

Try to figure out your headache trigger and prevent it.

Any sudden changes to headaches, such as migraines or other symptoms with a headache should be reported to you care provider.

12 Weeks Pregnant Ultrasound

Between 11 and 13 weeks pregnancy you may have decided to have an ultrasound scan.

This scan is to check on baby’s growth and development, so you may get to see baby this week!

During the ultrasound, the sonographer will measure baby from crown to rump.

This helps to determine if your baby is growing according to what’s expected at this gestation.

This ultrasound will also confirm your due date, plus or minus seven days.

About Your Estimated Due Date…

Remember your estimated due date is a guess.

It’s not predicting the actual day your baby will be born.

In fact, did you know only 3-5% of babies are born on their due date?

This is important to remember as you’re likely to get very tired of being asked ‘is the baby here yet?’ when you’re very pregnant.

It’s worth considering adding two weeks to your due date when telling family and friends.

Or even giving a due month rather than a date.

This way if you go over your due date (and chances are you will!) you don’t have to field all those messages.

There’s nothing worse than feeling like a watched pot when you’re 40+ weeks pregnant.

12 Weeks Pregnant – Your Body

Pregnancy hormones tend to shift at the end of the first trimester.

With your baby bump much more evident, it’s probably starting to hit you about the effects of pregnancy on your body.

Particularly your pelvis.

It’s never to late to start doing kegel exercises. These help strengthen the muscles which support your uterus, bladder and bowels.

Some women may feel a bit down about their appearance at the end of the first trimester.

If you’re one of those women who feel self conscious — please be kind to yourself! This too will pass.

If the finances allow, treat yourself to something special you enjoy and you will feel so much better.

A pregnancy massage is perfect for releasing stress and tension.

12 Weeks Pregnant – Your Baby

In week 12 of pregnancy, your baby’s sex organs are distinguishable, but still incomplete.

Your baby’s eyes are almost in the correct position in relation to its head, as are its ears.

The lungs are developing and primitive breathing can be seen. Vocal cords begin to form.

The amniotic fluid that your baby swallows is now passed out through its bladder.

Your baby’s bones, which until now were soft, are starting to harden, including the ribs and spine.

Its arms are in proportion with the size of its body. Toes and fingers are formed.

Movement will not be felt yet but your baby is still kicking away.

He or she can now curl their toes, rotate their ankles and wrists, press their lips together and make facial expressions, like frowning and smiling.

The umbilical cord is quite thick and still short. But as your baby continues to grow, the cord will lengthen and become thinner.

At 12 weeks pregnant, your baby measures approximately 4-5.5cms long, weighs around 14 grams and is the size of a lime.
