One month pregnant

One month pregnant - everything you need to know

Month one of your pregnancy…in which your nose takes on superpowers and you blab to a stranger.

Nipples on fire? Sense of smell so keen you can sniff a spritz of bleach 100 miles away? Does just one kind word set you off sobbing? Sounds like you're in the first few sensitive weeks of pregnancy.

Honestly, if a test doesn’t tell you you're expecting, then the bizarre symptoms that happen in the beginning will definitely have you thinking ‘hang on, what’s up with my body lately?’ as you start to notice the early signs of pregnancy.

Let’s talk about your sense of smell, and how everything stinks. You’re sitting in a really important meeting but all you can think about is the stench of your colleague’s BO. He’s not even sweaty. The workplace is a tricky environment for you right now. You can smell everyone and everything and it’s just plain weird. And that's just the beginning of the weird things you'll start to experience. 

One month pregnant: baby development highlights

 Here is what your baby is doing at one month:

1) Egg into an embryo!

When you get your late period, your body sheds its uterine lining and prepares a new one for the egg. One of your eggs will develop and ovulate.

2) Fertilising the egg

It takes up to three days for the sperm to meet up with your egg. Once the egg is in place, the sperm will race towards your egg. As soon as one sperm penetrates the egg's lining, your egg is now fertilised.

3) You now have an embryo

Your embryo will now go down the fallopian tube and grow into a ball about four days after conception. The embryo will move around until it finds its perfect spot to take base in the lining.

4) A bit of spotting

As the implantation process begins, it's likely you will have a bit of bleeding. To prepare for the early stages of your baby's growth and development, the placenta will also produce estrogen, progesterone, and human chorionic gonadotropin, which is referred as the pregnancy hormone.

5) The three layers are forming

Your baby is microscopic at this point, but, three cell layers are beginning to form.

The ectoderm layer will be your baby's nervous system, hair, and skin.
The endoderm layer, will develop your baby's gastrointestinal tract, liver, pancreas, and thyroid.
The mesoderm layer will develop into your baby's skeleton, connective tissue, blood system, urogenital system, and muscles.

What to expect now you're one month pregnant: 

Super sore nipples

Tight doorways, clumsy co-workers, or anything whatsoever that has the potential to make contact with your poor boobs right now.

Many women report sore or very tingly nipples as the first sign of pregnancy. They are so alert to all the changes going on that a simple breath of wind through your shirt can have you howling. It's down to the increased blood supply to your breasts and it will disappear as your body gets used to the hormonal changes.

Whatever it is, you might want to steer clear of crowded places for a bit. Even your own clothes are the enemy. We don't advocate going topless in public but we bet your bottom dollar you’ll be keen to strip your top half as soon as you’re behind closed doors.

Extreme tiredness

Extreme tiredness is a common symptom. Of course, it’s a bit embarrassing if you fall asleep when out and about but, when you crawl into bed in the evening or for an afternoon nap it’s like tucking yourself into the depths of a cloud and the best bit? You feel absolutely no guilt about it. Sleep, amazing baby-maker, sleep.

When you wake, the first thing you’ll think is ‘I’m pregnant’ and this is just about the only thing you’ll think about for a while.

There’s nothing quite like the buzz of excitement at being pregnant. Your heart wants to scream it from the rooftops but your mind might be telling you to calm down and keep things on the hush hush.

It’s a totally personal decision but one thing’s for sure - you’re walking around with that night before Christmas feeling every single day and there’s little else on your mind right now.

It’s either that, or you totally keep forgetting that you’re pregnant, you’re just getting on with your day, diligently working away and then BAM you remember, mid-sentence and have a ‘moment’ with a colleague when you start giggling at her very serious work talk or suddenly call her mummy, or something weird.

You'll be an emotional wreck

Oh, but would you mind not crying while you read this, please? It’s true that pregnancy can turn even the ice queens among us into blubbering wrecks. You'll experience an emotional rollercoaster from feeling glum and frustrated to jumping with joy. 

Now is the time to invest in a good waterproof mascara because everything from a puppy in the park to finding your favourite sup is on offer, will have you blubbing - get ready with your ‘got something in my eye,’ line if you’re not down with public displays of emotion.

And whatever you do, steer clear of that Davina show where she reunites long lost family members, it’s just too much for you right now.

Is my body changing already?

To take your mind off all this crying you could always shop for a few new clothes right about now, you know?

At around 4 weeks nobody else will notice any physical changes but you might feel a little bit like you’ve eaten all the bread.

Your body is making extra blood, you have more fluid and your hormonal activity will likely have you in that ‘I feel bigger’ headspace anyway, a bit like it does sometimes just before a period.

So it’s feasible that some of your outfits might begin to feel ever so slightly tight. Off goes the shopping Klaxon! You won’t be buying any official maternity clothes but how amazing to lust after elasticated trousers and feel happy about it?
