Week 7 of Pregnancy
Your baby is now the size of a blueberry, and major development is happening fast, tiny limbs are forming, and the brain is growing rapidly. You might notice stronger pregnancy symptoms as hormones surge and your body continues to adjust.
Baby’s Size
Your baby is about the size of a blueberry.
Baby’s Development at 7 weeks
Your baby's eyes
The main parts of the eye that allow your baby to see, the cornea, iris, pupil, lens, and retina, start developing this week, and they're almost fully formed just a few weeks later.
Brain development
The neural tube that becomes your baby's spinal column and brain has formed and closed on both ends, with your baby's brain at the top. It's now made up of three areas (forebrain, midbrain, and hindbrain). Amazingly, your baby's brain gains 250,000 cells per minute, on average, throughout the course of pregnancy.
Your baby's digestive system
Your baby's stomach and esophagus start to form. The esophagus is the tube that moves food from your baby's mouth to the stomach. Your baby's liver and pancreas are also starting to develop this week.
Pregnancy Symptoms during Week 7
-
Your body changes so rapidly during pregnancy that it's hard to know whether a new ache or symptom is "normal," or if you should call your healthcare provider or even head to the emergency room. And remember the bottom line: If you're worried, trust your instincts and get help.
-
Many newly pregnant women find that they're overwhelmed by gag-inducing smells. This may be a side effect of rapidly increasing levels of estrogen in your system. You may even discover that your partner, pet, or home smells unappealing now. But take heart, this heightened sense of smell is temporary, and will likely fade after early pregnancy.
-
You may suddenly find that certain foods you used to enjoy are now completely repulsive to you. Food aversions are another side effect of rapidly increasing estrogen levels. They often start during the first trimester and go away by the second, though it's possible that your appetite could be out of whack until your baby is born.
-
Needing to pee more often is one of the most common early signs of pregnancy. At this stage it's likely caused by hormonal changes that make your blood flow to your kidneys more quickly, filling your bladder more often.
-
Many pregnant women find that moodiness flares up around 6 to 10 weeks. Ricocheting emotions are likely caused by stress, fatigue, and hormonal changes. There's also the range of feelings you may have about becoming a parent.
-
You're not imagining it – it's normal to have more saliva when you're pregnant. You may be producing more or swallowing less – or a combination of the two. Hormonal changes, nausea, and heartburn can all cause you to salivate more during pregnancy. To cope, try brushing your teeth more often, eat small and balanced meals, and drink plenty of water. Also, sucking on hard candy or chewing gum may help you swallow.
-
Up to half of women experience constipation at some point during pregnancy. This happens because pregnancy hormones relax smooth muscles in the body, which means food moves through your system more slowly. You can combat constipation by eating high-fiber foods (like whole grains, fruits, vegetables, and legumes), drinking plenty of water, exercising, trying a different prenatal vitamin, and always going to the bathroom when you feel the urge.
-
Heartburn (also known as acid indigestion or acid reflux) is a burning sensation between the lower throat and the bottom of the breastbone. It's very uncomfortable and unfortunately unavoidable for some expecting moms. There are a number of things you can do to reduce heartburn: avoid food and drinks that upset your stomach, eat smaller meals, drink water in between meals instead of with them, chew gum, sleep propped up, and don't eat within two or three hours of bedtime.
-
By next week, 90 percent of expecting moms feel some pregnancy symptoms. But that's not everyone! If you don't feel pregnant (or have symptoms that come and go), rest assured that if you've had a positive pregnancy test, you're most likely pregnant. No one knows why some women have no pregnancy symptoms, but it doesn't mean that there's something wrong with your pregnancy.

Don't worry if you can't eat a well-rounded diet in your first trimester – nausea can make this impossible. Just do the best you can to eat well. Learn how to plan healthy meals while expecting, and check out these 15 delicious and nutritious recipes. Also keep in mind the 12 best foods for pregnancy: eggs, salmon, beans, sweet potatoes, whole grains, walnuts, greek yogurt, broccoli and dark leafy greens, lean meats and poultry, colorful fruits and veggies, avocadoes, and dried fruit.
-
Though you're carrying the weight (literally) of having a baby, there are many ways your partner can share in your pregnancy. The more bonding you do before the baby comes, the better equipped you'll be to handle the challenges of caring for a newborn together. Make time for date nights, talk about parenting, and share your hopes and dreams for the future.
-
Some expecting moms wait until after the first trimester, when the risk of miscarriage drops, while others announce it right away. Some wait to tell their co-workers or boss to avoid being treated differently at work, while others want their workplace buds to understand why they're a little green around the gills. Also consider how you'll make the news public – and get creative inspiration from other parents.
7 Weeks Pregnant Belly
Your belly may still look basically the same (especially hidden under loose clothing). Your growing breasts, on the other hand, may be telling a different story. Starting around now, you may notice your breasts getting noticeably bigger, and they'll continue to grow throughout your pregnancy. It's common to go up a cup size or two, especially if it's your first baby. Your breasts may feel itchy as the skin stretches, and you may develop stretch marks on them.
Tips & Resources
Focus on nutrition and hydration to support your baby’s rapid brain and organ development. Eating small, frequent meals can help manage nausea.
If you’re experiencing heightened fatigue, listen to your body and rest when needed.
