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 5 Weeks Pregnant
Your urine pregnancy test will be very positive at this point, but go ahead and take a second test just to be sure. By this week, you may be scheduling your first appointment with your health care provider. When you make this appointment, let the office know if you have any health issues that might make them want to see you earlier than usual. Let your health care provider know if you have experienced pregnancy complications in the past, if you have some medical problems that you think might affect the pregnancy, or if you’re taking any prescription drugs.
By week five, many women start noticing some breast tenderness. You may also start to feel more tired or have nausea. Some moms find that eating light snacks throughout the day, chewing ginger or drinking carbonated water helps to alleviate their morning sickness. Check out our complete list of mom-recommended of ways to help you manage your nausea.
If you haven’t already, it's a good time to start taking prenatal vitamins. Most over-the-counter prenatal vitamins are fine; other options include chewable prenatal vitamins or prenatal gummies. If you’re having trouble taking your vitamins because of nausea, you can take over-the-counter folic acid (or folate) tablets. This is the most important vitamin to take during this stage of your pregnancy. Try to take 800 micrograms of folic acid per day. When you start feeling better, you can go back to your regular prenatal vitamins. It’s also a good idea to take an additional 300 mg of an omega acid called DHA daily, and many prenatal vitamins will already have it. If not, try to take a daily additional fish oil capsule to satisfy this need. DHA is very important in the development of the baby's eyes and brain and should be taken during breastfeeding as well.
Your Baby at at 5 Weeks Pregnant
Your baby is now about the size of an appleseed. She is made up of several hundred cells and is attached to a yolk sac that provides her with early nourishment. You may be able to see this yolk sac on a vaginal probe ultrasound; the yolk sack will appear as a small white circle, but the baby is often still too small to see.
Amniotic fluid is beginning to form and surround your baby. Her heart is starting to form, and will be one of her first organs. Her cells will transform themselves into three main types of cells: the ectoderm, mesoderm and endoderm. Ectoderm cells will develop into her nervous system as well as skin, nails, and hair. The mesoderm produces many of your baby's inner cells, such as the heart, muscles, and bone. Finally, the endoderm produces the lungs, intestines, liver, pancreas, and the urinary system.
