Seems like just yesterday you found out you were going to be a mom. And it’s already your 7th week of pregnancy. How time flies! Your baby has come a long way from being the size of a pea to now that of a grape i.e. about 10mm long. Their brain is rapidly developing and soon your baby will start to feel temperatures and taste.

So are you excited to know more about how your baby is growing in the 7th week of pregnancy? Read the blog to learn more about what’s happening inside you this week.

Your Baby At Week 7

At week 7, your baby’s umbilical cord has formed which connects them to you. It helps support their nourishment and facilitates the transport of waste substances.

Their digestive system and lungs are still developing. And the eyelids and tiny arms are just beginning to form.

As the facial features such as mouth, nostrils, ears, and eyes are getting more refined, the face of your baby at 7 weeks is getting into shape. At this point, your baby has even formed a hand which looks like a teeny-tiny paddle. And soon, they’ll start making cute little movements.

The rapidly developing brain of your 7 week fetus makes them look like an alien, where the head is bigger than the body. You’d be surprised to know that they’re generating 100 new brain cells every minute.

At 7 Weeks Pregnant, How Big Is the Baby?

From the size of a pea in 6th week, your baby has now become the size of a grape. They now have a length of about 10 millimetres. But their forehead is much larger than the rest of the body, making room for the rapidly growing brain. And guess what, they weigh even less than an aspirin!3 4

7th Week Pregnancy Symptoms

You may notice the following symptoms in your 7th week of pregnancy:

Fatigue

It’s very common and totally natural to feel tired during early pregnancy. That’s because the levels of pregnancy hormones such as the human chorionic gonadotropins start to increase drastically. And it takes a while for your body to adjust to these changes. Also, there’s a lot that starts happening in the background that ultimately makes you feel more sluggish.

Morning Sickness

Morning sickness can occur at any time of the day in most pregnant women. It starts in early pregnancy and may last until the 16th week. For some women, it can continue across the entire pregnancy.

Urge To Pee More Often

Feel like you need to use the bathroom more frequently? This is mainly due to the hormonal changes that cause your kidneys to work harder and an increase in blood flow to the pelvic region.

Frequent Thirst

As you pee more often, your body’s fluid requirements also go up sending you frequent signals of being thirsty. Additionally, your body needs extra fluids to support the development of your growing fetus. The increased blood flow and metabolism further add to the heightened fluid demands.

Bleeding Gums

A higher-than-usual blood flow to your gums can make them swollen and sore. This could cause them to bleed more easily, especially while brushing your teeth.

Sore Breasts

The hormonal changes, increased blood flow and fluid retention make your breasts more engorged and sensitive to touch. These changes in your breasts can happen as early as Day 1 of pregnancy.

Your 7 Weeks Pregnant Belly

Your baby is too small yet to cause any noticeable change in your belly shape. And the bump would only start to show around your 17th week of pregnancy. However, those of you who have been pregnant earlier might start ‘showing’ a bit early.5

At around the 7th-week mark, your uterus has grown to the size of a lemon to accommodate the developing baby.1

Tips For When You’re 7 Weeks Pregnant

Here are a few tips that you’ll find helpful for your 7th week of pregnancy:

1) Stay Physically Active

Exercise is important for helping your body adapt to upcoming pregnancy changes and even labour. So try to engage in some physical activities as much as possible without exerting yourself. You can try doing light aerobic activities, swimming, cycling, walking and even yoga. But make sure you talk to your doctor before starting any new exercise routine during pregnancy.

2) Hydrate Well

Water helps transport nutrients to your baby, supports amniotic fluid levels, and prevents common issues like dehydration and constipation. So aim for at least 8-10 glasses a day to keep you and your little one healthy. You can also enjoy other fluids like fruit tea, fruit juice, skimmed or semi-skimmed milk.

3) Manage Nausea

Here are some tips that can help you deal with pregnancy nausea:

East a few soda crackers or dry toast as the first thing after you wake up.
Have a small snack before you sleep or when you get up in between sleep.
Have small frequent meals instead of a few large meals.
Drink plenty of water & other healthy fluids like soups.
Eat foods high in protein and complex carbohydrates (peanut butter with apples, nuts, crackers, etc.)
Avoid foods which are high in fat and salt.
Eat items made of ginger such as ginger tea, ginger candy, and ginger soda when you feel sick.

4) Get Plenty Of Rest

Prioritise sleep to help your body rejuvenate itself. Adequate rest supports your baby’s growth and keeps you energized throughout the day.

5) Take Your Supplements Regularly

Ensure you’re getting essential nutrients like folic acid, iron, and calcium to support your baby’s development and maintain your own health. But make sure to consult your doctor for the right dosage and recommendations.
