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 6 Weeks Pregnant
Most women with nausea will experience it in the morning. However, about one in three women will have more nausea in the evening. It's important to drink fluids during the times you are not nauseous in order to prevent dehydration. Taking over-the-counter Vitamin B6, 25 mg tablets, two to three times per day is safe and will often help. Foods containing ginger, as well as acupressure have also proved to be helpful. If your nausea is very severe, your health care provider can prescribe some medications that will help you feel better. If the nausea is affecting you greatly and you are becoming more and more dehydrated and weak, call your health care provider's office and ask to be seen as soon as possible. Your health care provider might suggest you receive intravenous fluids (an IV) to rehydrate your body. If your nausea is significant, you will lose some weight during this time. Some weight loss is normal, and usually not dangerous for the baby.
Your Baby at 6 Weeks Pregnant
Your baby is now about the size of a lentil. His organs are starting to form, and this process will continue for the next four weeks. This is a very sensitive time for your baby's development, so it's especially important to stay away from toxins and alcohol now. His heart is starting to beat, and his arms and leg buds are starting to form. In a week or two, you will be able to see your baby move. The placenta continues to grow into your uterus to establish your baby's sources of nutrients and oxygen.
