It’s week seven! Slowly but surely, all Baby’s important parts are starting to take shape.

How’s Baby?

Still growing like wild! Your Baby is now raspberry-sized and about half an inch long. For now, your little one’s head is the most prominent part of their body and looks big and round. And, incredibly, your baby’s brain is growing by about 100 cells a minute! Baby’s lower body is also starting to develop, and the presence of pre-legs and toes are starting to dominate their tail. Their tongue, ears, and eyes are also beginning to develop, and your baby is also starting to form the cartilage that will develop and harden into their bones. Other parts of their body are getting more complex as well, including their developing heart and kidneys, teeth, and the little paddles on the end of those arm buds that are destined to become Baby’s hands! You’ll be going gaga over their tiny fingers soon enough.

What's new with you?

One of the most common and notable symptoms of pregnancy at this stage is the increased need to pee. This is a result of both your growing uterus (now twice its normal size) putting pressure on the bladder, and the increased blood flow needed to sustain Baby’s healthy development. This increased frequency of urination is not likely to end anytime soon. In fact, as Baby grows, you are only going to pee more, and more often. One symptom that might go away soon? Nausea or morning sickness tends to recede by the middle of the second trimester for many people, thank goodness. By now, you’ll probably also notice an increase in the size of your breasts. Breast soreness and discomfort usually come right along with this, so you may want to think about switching up your bras if you feel that you need something more comfortable. Food cravings or aversions are also very common, due to the hormones that are coursing through your body right now. They may even cause acne or extra saliva.

While it’s possible that this could be a rough week in terms of pregnancy symptoms, don't worry if you’re not feeling any. Some folks just don’t, and it doesn’t necessarily mean that anything is wrong. If you are concerned though, you can mention it to your healthcare provider at your first checkup, which is probably coming up very soon.

And if you haven’t decided yet, now’s the time to figure out who you’d like to see for your medical care during pregnancy — whether a midwife, an OB-GYN, nurse practitioner, or a general practitioner — and to set up an appointment. Having a solid support system during pregnancy and afterwards is so important.
