Your Pregnancy: Week 5

Although you’ve been pregnant for four weeks now, you probably just found out. Congrats! Yippee! Woohoo! The fact that you’re actually growing a baby inside you probably seems completely surreal. Don’t worry, it’s common. Still, do your best not to overthink it. Instead, concentrate on making a nice home for the baby over the next nine months by taking care of you. That means eating right, moving your body (some call it exercise, but that sounds so strenuous) and taking it easy.

Wondering what’s up with your body, your baby and your life this week? Read on …

What You’re Thinking:

“If I order a club soda with lime on the rocks, I might be able to dupe my friends into believing that there’s nothing suspicious going on.”

Your body

If you never paid much attention to what you eat—we’re talking to you Ms. Cheeseburger and Fries—now’s the time to make it a priority to eat the most nutritious food you can.

The average pregnant woman needs about 300 extra calories each day. That’s right: extra calories! Being pregnant rocks!

Many insurance plans will pay for you to have a consultation with a qualified nutritionist or dietitian, who can help you create an eating plan that will work for you. That doesn’t mean you have to give up your vices and just eat boring health food all day. A nutritional plan will help you get the stuff you need for your baby first, then the rest can be icing on the cake. (Literally, you can eat icing if you want to. How great is that?)

Certain “super-foods” like walnuts and yogurt can provide extra bang for your buck, giving you and your baby much-needed nutrients in each bite. Walnuts dipped in icing anyone?

Your Baby

Your baby’s microscopic heart begins to beat this week—although it won’t be detectable with one of those cool Dopplers for a few weeks, so you’ll have to wait a little longer to hear that satisfying “whoosh-whoosh” you’re so anxious for. Here’s what else is under construction:

With the beating of the heart, blood will begin to circulate throughout the body. Your baby’s first organ system will be up and running!

The beginnings of the brain; the cardiovascular, nervous and reproductive systems; as well as all other major systems are under way.

Your baby’s new digs—the amniotic sac and the placenta (aka the hotel and the restaurant)—are still forming at this point. (Maybe you should send a housewarming gift.)

All that high-speed development and your baby is only 2 millimeters long—about the size of a sesame seed (check one out next time you’re chowing down on a bagel—you won’t believe how tiny it is!).

Your Life

Don’t wait until the baby arrives to invest in a good point-and-shoot digital camera. (It’ll probably take you at least nine months to figure out how to use it anyway!) If you don’t already have one, check out Consumer Reports to find the model that’s right for you.

With your new camera (or with the one you already have), start taking pics of your growing belly week after week. After it’s all said and done, you won’t believe you were ever that big (or this small).

Make a list of all the things you want to do before the baby arrives. Want to go to France? (Or even the outlet mall in the next town over?) Start planning, because the next several months will be prime time to get in as much as possible.
