1 Week Pregnant Symptoms And Helpful Self Care You Should Know

1 Week Pregnant

Soon-to-be moms need to know what to expect throughout each stage of pregnancy because specific factors about bodily changes to dietary requirements to general well-being tips define each one.

In this article, we’ll look at pregnancy week 1, covering what that means and how to support a healthy pregnancy.

What happens when you are 1 week pregnant?

At pregnancy week 1, you’re technically not pregnant just yet.

‘Week 1’ is a term that medical professionals use to refer to the first day of your last menstrual period. Referring to this stage as week 1 helps doctors estimate your due date.

That means that no conception (sperm meets egg) has happened yet. Still, after the last menstrual period, your body is already gearing up for conception by preparing the uterine lining and starting the process of ovulation.

So, at this stage, you’re 0 months pregnant. 

Over the coming weeks, your body will release a key hormone for conception known as the follicle-stimulating hormone or FSH. This hormone signals the ovaries to start growing follicles in each ovary.

Before ovulation, the body thickens the uterus lining to house a fertilized egg. 

During ovulation, which happens around 14 days after your last menstrual period, one of these follicles will release the ovum.

Pregnancy symptoms at week 1?

Pregnancy symptoms at week 1 are similar to your regular period because you’re technically not pregnant yet. 

Some women experience significant PMS symptoms, while others have mild symptoms. 

Symptom severity ranges widely between individuals.

Common symptoms you may experience at one week pregnant, 0 months pregnant, or during menstruation last for three to seven days and include:

1. Bleeding

Vaginal bleeding occurs as a result of the shedding of the uterine lining. The lining had built up over the previous month to support a fertilized egg, but since there had been no conception, the old lining sheds to make room for the new.

2. Bloating

You may notice a bloated belly before and at the beginning of the week of your period. You may feel like you’ve gained weight or that some body parts feel swollen. 

Bloating tends to subside shortly after menstruation begins.

3. Lower back and abdomen pain or cramps

The uterus is a muscular organ, which means it can contract. 

It must contract to release the uterine lining, but these muscular contractions lead to pain for many women. This pain is primarily experienced in the abdomen and lower back.

4. Mood swings

Menstruation involves a range of hormonal surges and fluctuations in the body, which can affect a woman’s emotional state. As such, you may notice increased irritability or more emotional ups and downs than usual.

5. Headaches and migraines

Other hormone-related symptoms many women experience are menstrual headaches and migraines. These are among common menstruation symptoms but can feel debilitating for some. 

OTC pain relievers, minimal exposure to bright lights and other stimulation, and simple relaxation exercises can help ease PMS-related aches and pains.

Self-care for mom in week 1

For expecting mothers, it is important to care for your body and mind, as both will endure challenging times throughout the pregnancy. 

Growing a little human inside you is an unparalleled joy, but mothers know this is no small feat.

We’ve heard the basic advice, the ‘take a shower’ and ‘rest’ messages offered with good intentions but don’t cover proper self-care for expecting moms. 

The fact is that there are many more ways you can and should take care of yourself during this beautiful, challenging, and life-changing experience.

1. Learn about the stages of pregnancy

One of the most important steps you can take in the direction of real self-care is to learn as much as you can about the stages of pregnancy to know what to expect and understand what’s happening at each stage.

Speak to a health care professional such as your local GP or obstetrician, or seek the advice and experience of trusted friends and loved ones who have already been on the journey. 

Find out as much about pregnancy self-care to keep your mind and body in a healthy and safe space. (Reading this article is a great start!)

2. Know the signs of pregnancy

You won’t experience specific pregnancy symptoms during the first week of pregnancy. Instead, you’ll experience the symptoms of your regular period. 

However, over the coming few weeks, you’ll start to notice early pregnancy symptoms, such as:

  • Missed menstrual period
  • Nausea
  • Breast tenderness, swelling
  • Headache
  • Frequent urination
  • Raised body temperature
  • Pelvic discomfort
  • Mood swings
  • Cravings/aversion around food
  • Metallic taste

Experiencing the above early pregnancy signs does not mean you’re pregnant. 

But if you’re pregnant, you’ll likely experience these symptoms. 

Don’t rely on symptoms alone to determine if you’re pregnant, as symptoms vary widely among individuals. 

A home pregnancy test is the best way to check for pregnancy.

3. Arrange a preconception visit

One of the most helpful self-care tips for potential mothers is seeking professional advice. Taking the initiative to approach a professional and learn as much as possible about pregnancy and keeping ourselves healthy is a mature and responsible way of ensuring everything goes smoothly. 

So, schedule a visit with your doctor before getting pregnant and ask them how you can best prepare.

4. Be mindful of your diet

Keeping your body as clean and healthy as possible is essential to increase the likelihood of a healthy, worry-free pregnancy. 

So, assess your diet and general health habits and see what aspects may be best to avoid moving forward.

Tobacco, alcohol, and excessive caffeine consumption risk a potential baby’s health and reduce fertility. 

It’s best to curb these habits before you’re expecting rather than waiting until you’ve got a positive pregnancy test. 

It’s recommended that pregnant women and women who are attempting to conceive take a daily prenatal vitamin with 400 mg of folic acid (folate).

5. Don’t sweat the small stuff

Perhaps the most important advice to any expecting mother is to relax as much as possible during pregnancy. Yes, ‘relax’ is one of those cliché self-help tips that doesn’t always hold weight. 

Still, the fact is that relaxation – cultivated through relaxation exercises, breathwork, and limited physical exertion – is what’s going to help you get through the more challenging aspects of your journey to motherhood.

To help you relax during your journey, ensure you have easy access to things you enjoy doing, perhaps a hobby such as painting or reading. 

A relaxing hobby is a great way to keep your mind healthy and your body calm while you grow this new life inside of you.

Week 1 of Pregnancy FAQS

It’s normal for women expecting and trying to conceive of having plenty of questions about pregnancy and how to do it right. 

Below we’ve answered some common pregnant questions based on pregnancy week 1.

1-week pregnant belly size

Pregnancy evokes images of a huge baby belly, but you won’t notice a bump at week 1 (because you’re technically not pregnant yet). 

It will take a few weeks to months after conception before the pregnant belly starts to show. 

However, due to hormonal fluctuation and fluid retention around menstruation, you may notice some bloating during pregnancy week 1.

Can morning sickness start at 1 week?

Morning sickness is a hallmark sign of pregnancy. 

Some women may experience some nausea and discomfort at pregnancy week 1, but morning sickness typically shows up as a pregnancy symptom sometime between week four and week nine.

Should I start taking prenatal vitamins in week 1?

Yes, you can start taking prenatal vitamins as soon as you plan to conceive. 

You should take them daily, and you can even start taking them around a month before trying to conceive. You should continue to take prenatal vitamins during the first three months of pregnancy because this is a critical time in the baby’s development.

Mothers should also take prenatal vitamins throughout pregnancy and through breastfeeding. Getting the right amounts of vitamins and minerals, especially folic acid (folate), in your diet is an excellent way for both mother and baby to stay as healthy as possible.

Folic acid is one of the essential vitamins for pregnant women. This B vitamin (B9) significantly reduces the likelihood of congenital disabilities by supporting the formation of the neural tube, which forms the early brain and spine.

What should I avoid during week 1 of pregnancy?

Even though pregnancy week 1 is not an actual pregnancy, it’s still wise to avoid certain foods and substances in week 1. The first three months (the first trimester) is an incredibly sensitive time in the baby’s development, so it’s wise to avoid the following:

  • Smoking and alcohol
  • Excessive caffeine use
  • Raw or undercooked meats and eggs (incl. processed and deli meats)
  • Some seafood and shellfish
  • Unpasteurized dairy products

In terms of healthy lifestyle choices for expecting mothers, avoid the following in the first trimester:

  • Significant weight gain
  • Saunas, whirlpools, steam rooms
  • Massage and acupuncture
  • Cat litter (may contain parasite Toxoplasma gondii, associated with miscarriage, stillbirth, and congenital disabilities)

How can I tell if I’m pregnant after one week?

You won’t notice the signs of pregnancy until you’re at least a few weeks pregnant, so any symptoms you notice in pregnancy week 1 are more likely related to your menstrual cycle than pregnancy. 

For most people, the first noticeable sign of pregnancy happens around week 4.


Pregnancy is a life-changing journey that women have the honor to experience. As beautiful as it is to create a new life, the journey is not without its challenges. 

Soon-to-be moms can give themselves and their babies the best chance of a successful pregnancy by adhering to a healthy diet with plenty of vitamins and minerals, especially B12 (folic acid, folate), avoiding toxic substances, and relaxing the mind and body as much as possible. 

Finally, don’t hesitate to speak to a medical professional if you have concerns about your or your baby’s health during pregnancy.
