Pregnancy at 1 Week

Congratulations on your pregnancy! Welcome to your journey to motherhood. We’re honored to help guide you through the process. At the Round Up, you’ll find many resources to help you: whether it’s your changing body, your baby’s development, how to prepare your home, how to tell those you love, or even just what to register for when it’s time for your shower, it’s all here for you and your baby.

It’s time to schedule your first prenatal appointment with an OB/GYN or a midwife whom you know and trust. Even before your appointment, be sure to ask your health care provider about whether the medications you’re currently taking are safe to take during pregnancy.

If you haven’t already started taking prenatal vitamins, which contain important elements like calcium and folic acid for the health of your growing baby, now is the time to start. There are a decent variety of prenatals to choose from in stores, so you now have the option of a gummie vitamin, pill or powder that you add to your water.


Since you’re pregnant, it’s also time to start avoiding drugs, alcohol and excessive caffeine (about 150 mg of caffeine per day is the safe limit according to the American Pregnancy Association.

Your Body at 1 Week Pregnant

You may still have your period, at this point, but five to 10 small follicles (or sacs) are growing inside your ovaries. Each one contains a single egg that’s too small to see even with an ultrasound. Next week, one of these growing follicles will grow larger than the others and become the dominant follicle, and the remaining follicles will stop growing.

Your Baby at 1 Week Pregnant

You have 40 weeks to go! Most pregnancies last 40 weeks from the first day of your last period so the first week of your pregnancy starts from that day, even if in reality conception happens two weeks later. During the first week, the egg that will become your baby is now growing in a small fluid-filled bubble called a follicle or sac that resides in your ovary. The follicle will grow close to one inch by the time it pops open and releases its egg. This is called ovulation. About 10 other competing follicles, each with its own egg, are growing at the same time within your ovaries.
