Although you might not be looking much different at five weeks pregnant, aka two months pregnant, your hCG hormone levels are now high enough to confirm that you’re expecting with a home pregnancy test and you're only around seven to eight months away from holding your baby in your arms!

If you've just taken a pregnancy test that is positive, you might be feeling a lot of emotions. Whether it's excitement, fear or worry of the unknown, or disbelief, any emotion is completely normal. The best way to make everything feel less scary is to read and prepare yourself.

In this article:

  • Find out how big your baby is at five weeks

  • What symptoms will I be feeling?

  • See what your baby is doing at five weeks

  • Ask the expert your frequently asked questions

  • Things you should be doing now

There's plenty going on inside your belly at five weeks pregnant, and your little baby is now transforming from an embryo to a fetus. Your placenta is also still under construction too. And with all this going on inside, you're likely to be feeling some of the side effects of your pregnancy, such as tiredness and maybe even nausea.

How big is my baby at five weeks?

Your little embryo is now the size of an orange seed and looks similar to a tadpole with a tiny head and tail. They won't stay this tiny for long however, as in the next week, he or she will almost double in size going from 2mm to 4mm!

What symptoms will I experience?

By now, you should have missed a period and have taken an at-home pregnancy test with a positive result. Realising that you will soon have a little baby to take care of can leave you feeling all sorts of emotions from sheer joy to panic, so its normal if your moods are all over the place.

1) Food cravings

It might be early days, but the food cravings might already be kicking in. Hormones play a part here, so try and relax and go with it as your body gets used to the hormone havoc!

That said, indulge your cravings within reason and make sure you’re getting healthy substitutes for the foods you can’t stand.

What's my baby doing at five weeks pregnant?

During this week, your baby is growing its blood, kidney and nerve cells, heart, and gastrointestinal tract. This is also when your baby’s brain and spinal cord will form. While the baby is growing this, you will be growing the primitive placenta and umbilical cord.

Your baby’s heart is made up of two tiny channels and they’re already working. Once those tubes fuse together at some point this week, your baby will have a fully functioning heart.

The placenta still hasn’t fully formed, so at the moment your little one is feeding on something called the ‘yolk sac.’

Your frequently asked questions answered by a midwife

Alison Quincey-Brooke is a midwife of 24-years and she said: "At 5 weeks we don't tend to see women as it's early in gestation. Normally we first see women around 8 weeks for their first booking appointment. 
If you need monitoring closely due to a medical condition or very anxious due to a previous pregnancy loss or an assisted conception, then we would be more likely to see pregnant women at 5 weeks."

If you're worried because you recently had a glass of wine, then don't worry. Unknowingly drinking in very early pregnancy is not uncommon, and you have no reason to panic.

It’s natural to feel daunted, and combined with the cocktail of pregnancy hormones racing around your body, it’s no wonder you’re feeling a little all over the place.

What to do now...

See your GP: The next thing for you to do now is to book an appointment at your local GP to see a midwife or be referred to one. From there you'll be told about when your next appointment will be and offered screening tests for infectious diseases, and conditions such as Down's syndrome.

Avoid eating certain foods: Throughout pregnancy, there are certain foods you shouldn't eat such as soft cheese, undercooked meat, eggs, and some kinds of fish that are high in mercury. It's important to make these changes as soon as you find out that you're pregnant. Food aversions can make it difficult throughout pregnancy when it comes to meals, but eating healthy is important, so have a look at what foods are good for you in the first trimester.

Don't skip that evening floss: A lot of pregnant women suffer from gum problems during pregnancy thanks to the extra blood surging around your body. It's important to take care of your teeth, so brush regularily and floss after food as well.

Exercise safely: If you're keen to do some exercise or the morning sickness is getting worse, go out for a brisk walk. Pelvic floor and core exercises are safe to do as well, but make sure you don't lie on your back.

Consider getting a flu jab: Being hit with the flu when you are pregnant can make you very poorly and sometimes develop into pneumonia so many experts recommend pregnant women should get the flu jab as a precaution.

Have a cat? If you’ve got a cat, it’s time to hand over the litter cleaning duties for the next eight months (not that you’ll be complaining). Cat litter is dangerous as it can cause an infection called toxoplasmosis, which can harm your unborn baby.
