15 Weeks Pregnant – Everything You Need To Know

15 Weeks Pregnant - Everything You Need To Know

You’re 15 weeks pregnant!

The good news is you’re probably feeling much more energetic.

The tired fog you’ve been living in has lifted and you’re not experiencing pregnancy brain as much.

Morning sickness is likely a thing of the past now.

Many women are feeling so good at this point of their pregnancy they begin to experience an increased libido.

Some pregnant women may not want sex at all.

At the opposite end of the spectrum, others might have the highest sex drive they can remember!

This might be a little surprising to you but pregnancy really has a huge impact on your body.

15 Weeks Pregnant – Everything You Need To Know

Pregnancy increases the blood flow, particularly to your breasts and pelvis.

This increased blood flow can make these areas more sensitive and you may become aroused more easily.

At 15 weeks pregnant you’re also more likely to start really enjoying your body.

Weight gain during pregnancy is normal.

Unfortunately society has pushed the ‘perfect’ body image on to women and we’re critical of ourselves, even when we’re pregnant.

Some women find their changing body different and are challenged to see its beauty and strength.

Other women might find their rounder hips and breasts make them feel sexier.

This is perfectly normal! And it can often mean you are more interested in and have an increased response to sex.

If you are having a normal pregnancy, it’s perfectly safe to have sex during this time.

Take advantage of this increased interested in sex. It’s a great way to connect with your partner on an emotional and physical level.

If your partner is resistant to having sex while you are pregnant, it could be he’s feeling strange about the baby being so close to the action.

Reassure him the baby can’t feel or sense what is going on.

You may need to take the initiative in this department until he becomes more comfortable with it.

15 Weeks Pregnant – Your Body

You may start to experience some new symptoms in week 15 of pregnancy.

A less than desirable affect of pregnancy is increased nosebleeds.

Thanks to the pregnancy hormones progesterone and estrogen, your blood vessels are dilating more easily.

Your blood supply has increased.

This puts pressure on the small capillaries found in the lining of the nose and the gums.

As a result, this causes nosebleeds and bleeding gums.

Try to avoid letting your nose dry out, especially if you spend a lot of time in places with central heating.

Running a humidifier in your home (especially in winter) may help.

Lubricating the nostrils can also alleviate the nosebleeds.

A simple ointment like paw paw or vitamin e cream can help to keep the sensitive nasal passage from drying out.

Swollen gums are a common pregnancy symptom. They become very sensitive and may bleed when you brush or random.

It’s hard to prevent bleeding gums.

A diet rich in protein, calcium and vitamins C, B and D may help.

It’s important you take good care of your teeth and gums at this time, as you can be prone to gingivitis (inflammation of the gums) during pregnancy.

Left unchecked, gingivitis can cause periodontitis (infection of bone and tissues supporting the teeth).

Research has shown this to be a risk factor for premature labour.

Good dental hygiene is a must, so see your dentist at the first sign of problems.

Nutrition Needs At 15 Weeks Pregnant

You might find around this time you start to feel a little short of breath.

This is because your growing uterus and baby are starting to take up more space.

Your lungs might be finding it harder to expand to take a deep breath.

But if you’re feeling very short of breath and are still very tired, you might be low in iron.

A simple blood test can check your iron levels, both stored and available.

It’s normal for iron levels in your blood to drop as your pregnancy progresses.

This is because your blood volume expands.

However if you don’t have enough stored iron to cope with this decrease you can begin to feel the effects of pregnancy anaemia.

Usually low iron isn’t a problem for most pregnant women. It’s a good idea to ensure your diet includes plenty of bioavailable sources of iron, especially if you are vegetarian or vegan.

15 Weeks Pregnant – Your Baby

When you’re 15 weeks pregnant, your baby is moving around a lot.

You might not have noticed these movements yet.

But sooner or later you will feel something which makes you wonder!

These movements can’t be seen from the outside. But you may start to sense very light fluttering in your belly.

Almost like a muscle twitch or butterflies in your stomach.

It’s quite busy in there, with your baby curling fingers and toes, while kicking legs and waving arms.

Your baby is becoming sensitive to light now and may even get the hiccups!

Baby’s skin is still very thin and see through.

Respiratory type movements in your baby’s chest can be detected now.

Your baby is moving about half a litre (one pint) of amniotic fluid in and out of the lungs every day and excreting about the same amount of urine.

And your baby is starting to develop what is known as ‘brown fat’.

This fat helps your regulate body temperature and is very important after birth.

Your baby’s legs have grown enough that they are as long as, or longer than his arms, making him look more proportionate.

You’re starting to look more pregnant now because your baby is growing fast.

And at 15 weeks pregnant your baby is starting to look more like the bad you’re imagining. Ears have migrated to the side of the head. Your baby’s eyes are moving from the side to the front.

Your baby is around 10cm long and weighs about 70 grams. He is about the size of a navel orange.
