1 week pregnant: advice, symptoms and what to expect

by Maria Martin |

There’s no embryo yet, just your egg and hopefully sperm ready to fertilise it, but at one week pregnant are there any symptoms?

What advice can you follow when trying to conceive and what should you expect?

This will be the week immediately following your last period and your body is getting ready to ovulate.

So, even though you haven’t actually conceived at this point, this is your first week of being pregnant.

What's happening in my body?

The average menstrual cycle lasts around five to seven days.

What you shed during this time is a combination of the lining of your womb (called the endometrium) and actual blood.

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

1) 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 women who get 300 micrograms of folic acid reduce the risk of neural tube defects by up to 70%.

The symptoms

When you're 1 week pregnant, you might experience the following symptoms:

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

  • Cramps and pain in the lower back - shedding your lining comes with some pain in your lower back as your uterus contracts.

  • The period feeling - you will feel a bloated tummy which you normally get before your period.

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

  • Headaches - someone women will experience headaches like 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 any time in pregnancy, but it is most common early on.

What is my baby doing?

Right now, there is no baby and you won’t know for sure if your egg has been fertilised for another month.

Medical professionals will use the first day of your last period as the start of your pregnancy, as it’s impossible to know exactly when you conceived.

How can I work out my due date?

As a rule, you’re ovulating around two weeks after the first day of your last period.

Your egg will usually be fertilised around 24-36 hours after ovulation.
