5 Weeks Pregnant – What To Expect In Week 5

5 Weeks Pregnant - What To Expect In Week 5

At 5 weeks pregnant you’re now likely to suspect, or know, you’re pregnant.

You might have done a home pregnancy test.

Sometimes the line on the pregnancy test is quite faint.

This could cause you to worry about whether or not you’re actually pregnant.

If you need to squint to see the line, be sure to read Faint Line On A Pregnancy Test – What Does It Mean? for more information.

Emotions When You’re 5 Weeks Pregnant

It’s normal to feel a variety of emotions when you first find out you’re pregnant.

You might be elated because it happened more quickly than you thought.

Or you might feel worried about the future, and whether you’ll cope as a parent.

It can be a massive adjustment, as you come to terms with the news that you’re pregnant.

How you and your partner react to the news you are expecting is very individual.

It might take some time for the initial shock to wear off.

You or your partner might even feel overwhelmed, lost and anxious.

Enlist the support a trusted friend or family member.

Or you could seek help from your doctor, a counsellor or a support service that deals with pregnancy crisis.

5 Weeks Pregnant: Symptoms

This week of pregnancy is the first week after your missed a menstrual period.

At 5 weeks pregnant, pregnancy hormone levels begin to increase.

Your levels of progesterone have gone up. This stimulates blood vessel growth in the uterus, which results in a healthy placenta.

This extra blood vessel growth also happens in other parts of the body, and gives you that ‘glow’ pregnant woman are famous for.

There’s likely to be some tenderness in your breasts and nipples.

Other signs of pregnancy you might notice at 5 weeks are:

  • Food cravings
  • Frequent urination
  • Fatigue – not just tiredness but an intense need to nap wherever you are
  • Mood swings.

You might not experience any or all of these symptoms of early pregnancy right now. They can start at different times for each woman.

5 Weeks Pregnant Cramping

Pregnancy is a time of radical transformation within your body – even in the early weeks.

Your uterus is preparing to hold a growing baby.

Some women have regular menstrual cramps, either in the pelvis or as a constant, low backache.

Experiencing the same sensations during pregnancy can be a bit worrying.

You might feel the sensation and expect a period-like flow to begin. It might lead you to be concerned about miscarriage.

Prior to missing a period, some women notice cramping from implantation.

At 5 weeks pregnant, cramping is associated with the expansion of the uterus.

Although there’s not a great deal of uterine growth just yet, these small changes can cause cramping.

Cramping without bleeding is usually not a concern. Contact your care provider if you have any of the following:

  • Severe pain
  • Cramping with bleeding (menstrual like flow)
  • Localised pain.

If you have any concerns, always see your care provider as soon as possible.

5 Weeks Pregnant Belly

You might be wondering whether it’s possible to feel your baby at 5 weeks pregnant.

Your baby is growing rapidly but is still very tiny.

Consequently you won’t feel movement for many weeks.

However, women who’ve been pregnant before might feel a heaviness or fullness in their bellies.

In fact, as early as 4 to 5 weeks pregnant, many mothers feel the urge to urinate more frequently.

This is due to increased blood volume, which makes your kidneys work a bit harder.

They expand to deal with this increase in blood, and push on your bladder.

So it’s not your baby crowding things in there just yet. That will happen later.

Do you own a cat? Do you keep its litter box in the house?

While you’re pregnant it’s best to avoid cleaning the litter box.

In some cats’ faeces, there’s a parasite that causes toxoplasmosis, which can lead to serious health problems for your baby.

The good news is you don’t need to get rid of your cat. The other good news? Your partner can be assigned to kitty litter duty.

5 Weeks Pregnant Ultrasound

An ultrasound at 5 weeks pregnant is not common unless you have medical concerns.

Most ultrasounds done at this early stage are to determine whether the fertilised egg has settled in the right place.

A gestational sac, which is one of the first signs of pregnancy to be detected on ultrasound, might be visible.

The gestational sac is seen before a recognisable embryo can be detected. Usually, by 5 weeks pregnant a yolk sac is also visible inside the gestational sac.

However, it’s important to know this ultrasound is not abdominal; it is done with a trans-vaginal probe.

Abdominal ultrasound is much less accurate so early in pregnancy.

5 Weeks Pregnant: Your Baby

At 5 weeks pregnant, your baby’s development is happening at a cracking pace.

In the centre is a tiny bud, which will develop into organs, bone and muscle.

Your baby’s heart is the first organ to start functioning. It has divided into two chambers and begun beating.

Your baby’s brain, circulatory system and thyroid gland have also started to develop.

The neural tube is closing and will protect the developing brain and spinal cord.

Folates are important at this time, to prevent neural cord defects. Pregnant women are recommended to take prenatal supplements with folic acid in them.

This can be a problem if you can’t convert synthetic folic acid into a useable form. If so, you should take folinic acid. You can read more in Folate – Why It’s So Important Before And During Pregnancy.

The placenta and umbilical cord have developed and are helping to nourish your new baby.

They are responsible for pumping in nutrient-rich blood and oxygen, and expelling waste. Pretty impressive!

At five weeks pregnant your baby is only 3mm long, which is about the size of a sesame seed.
