1 week pregnant

Things are about to get exciting, mama-to-be; you're 1 week pregnant! There’s no embryo yet; it's just your egg and, hopefully, sperm ready to fertilise it. However, this will be the week following your last period, and your body is preparing to ovulate.

So, even though you haven’t actually conceived at this point, you are considered 1 week pregnant. Here's everything you need to know...

How many months is 1 week pregnant?

Counting pregnancy in weeks and months can get a little confusing. At one week pregnant, you're not quite a full month into your pregnancy. Pregnancy is typically measured in weeks, with the first month of pregnancybeing roughly equivalent to 4.3 weeks.

Baby Development at 1 Weeks Pregnant

At one week pregnant, there's no baby just yet. Your body is simply going through its usual process of shedding the uterine lining from the last cycle, which is what happens during your period.

When you’re pregnant (around four weeks pregnant), the fertilised egg will settle into the uterus, starting your baby's development. Your baby is still a cluster of cells at this early stage, but over the next few weeks and months, they'll begin laying the groundwork for growing their organs and tiny features.

Feeling excited? Why not take a look at what to expect at two weeks pregnant?

Your Body at 1 Week Pregnant

The average menstrual cycle lasts around five to seven days. During this time, you shed a combination of the lining of your womb (called the endometrium) and actual blood.

Here’s the scientific part: the hormone changes that stimulate your period also encourage the brain to produce luteinising hormone (LH) and follicle-stimulating hormone (FSH), both of which are key to helping you get pregnant.

When you're one week pregnant, you might experience the below symptoms. Don't worry if you don't, though - it's early days, and not all of these symptoms are unique to pregnancy either.

Vaginal bleeding - the vaginal bleeding will come as your body is now shedding the uterine lining.

Stomach pain, cramps and pain in the lower back - shedding your lining comes with some pain in your lower back as your uterus contracts.

Bloating - you will likely feel a bloated tummy, which you may be used to experiencing before your period.

Mood swings - your emotions will be rather high, all thanks to your hormones.

Headaches - some women will experience headaches as they do with periods.

Acne or pimples - whether you had acne as a teen or not, you might get acne or pimples early on in pregnancy. Try natural solutions to treat it.

Fatigue - Fatigue can happen at any time during pregnancy, but it is most common early on.

Getting pregnant timeline

Day 1: The first day of your period

Day 14: You ovulate. This could happen slightly before or after, depending on the length of your menstrual cycle.

24 hours after ovulation: If you have had sex in the last few days without using contraception, the egg is fertilised by sperm.

5-6 days after ovulation: The fertilised egg implants in the womb - you are now pregnant.

Looking After You at 1 Week Pregnant: What You Can Do To Help Your Body Conceive

Get to know when you're ovulating

Knowing exactly when you’re ovulating can help you conceive. We’ve developed a handy ovulation calculator.

Start taking folic acid

To protect your future baby from spina bifida, medical experts recommend you start taking folic acid for three months before you want to conceive. Research also suggests that women who get 300 micrograms of folic acid reduce the risk of neural tube defects by up to 70 per cent.

Eat a healthy, balanced diet

Your fertility diet must give you all the nutrients you need, especially zinc.

Cut down on the caffeine

Your morning latte is fine but try and limit your caffeine consumption to no more than three cups a day.

Quit smoking

Quit smoking and cut down on alcohol if you’re trying to get your body ready for a baby.

Protect his sperm

Discourage him from taking steamy hot showers or baths, as this can affect sperm quality. The bath water should be no hotter than the body temperature for optimum sperm. It’s also a good idea for you to turn that electric blanket off and stop putting your laptop on your lap – studies show prolonged and excessive heat can slow down sperm collection.

It's time to get zen

Whether you book a few extra yoga classes or download a meditation app. If you’re stressed, you’re biologically less likely to get pregnant.

Book a doctor's appointment

Although you’re not pregnant, it’s a good idea to schedule an appointment and talk about prescription drugs and environmental and lifestyle hazards that could all be putting your baby-to-be at risk.

When to take a pregnancy test

You can take a pregnancy test up to five days before your period is due. During the early days of pregnancy, your HCG levels rise rapidly, so if you want as accurate a result as possible, do the pregnancy test on the day of your missed period.
