Your Baby at 5 Weeks Pregnant
Your little one is the size of a small orange seed (length: 0.05-0.1”).
Pipeline in place. The placenta and the beginnings of the umbilical cord are already working hard to channel essential nutrients from your body to the embryo. Oxygen, amino acids, fats, and sugars all play a vital role in healthy development.
Back basics. Some of the cells are developing into the neural tube, which will become the spinal column and the brain. An incorrectly formed neural tube can result in spina bifida (a complication in which the spinal cord doesn't fully close) or other related disorders. Taking at least 400 micrograms of folic acid every day is your best weapon against spinal cord-related birth defects.
Heart start. The heart is now a single tube with a few uncoordinated beats. These thumps will become more regular with each passing week.
Your Pregnancy at 5 Weeks
An ocean of emotions. How do you feel now that you're actually pregnant? If you've been trying to conceive for a while, you're probably ecstatic. You may also be anxious, wondering whether everything will go normally. If the pregnancy was a surprise, you might feel worried or unsure of yourself. All of these emotions, from wild elation to maternal pride to gripping fear, are perfectly normal.
Handle with care. Menstrual-like cramps and lower backaches are common at this stage. Give yourself a break by soaking in a warm bath, listening to some soothing music, or indulging in a nap. If you haven't done so already, now's the time to cut out smoking, drinking alcohol, or using drugs — these can be harmful to your little one.
