If you haven’t already, go ahead and schedule that first prenatal appointment. While you’re on the phone, ask for a prenatal vitamin recommendation, and find out whether the medications you’re currently taking are safe for your baby.
Start taking your prenatal vitamins, if you haven’t already, and continue to avoid drugs, alcohol and excessive caffeine. About 150 mg of caffeine per day is the safe limit according to the American Pregnancy Association, if any. You’ll want to stay away from all three during your pregnancy.
Your Body at 7 Weeks Pregnant
You’re probably weary of nausea by now, but it may last for a few more weeks. Still, your pregnancy symptoms, such as nausea and breast tenderness, may often fluctuate at this point. You might even have days when you have few pregnancy symptoms. It's common to feel tired at this stage, and this fatigue often remains for next four to six weeks.
Your Baby at 7 Weeks Pregnant
Your baby is now about the size of a blueberry! Her liver is producing red blood cells until the bone marrow forms. Her pancreas is starting to form and will soon start producing insulin as well as other proteins that will help with digestion. Her arm and leg buds continue to grow. Blood vessels are now present all throughout the body, and the blood vessels under the thin skin are now visible. Her heart is starting to divide into individual chambers. Her heart rate is now about 140 to 160 beats per minute (about twice as fast as yours). The early spinal cord, called the neural tube, is growing will eventually lead to her nervous system and brain.
