Your baby is rapidly growing and will triple in size this week. Basic facial features such as eyes and ears are becoming more developed and the neural groove will have closed by this time. The tiny heart is starting to pump blood.
Along the midline, 40 tiny blocks of tissue are developing which will eventually become the backbone, ribs, and muscles of your baby's back and sides.
As it's still early in the first trimester you may not notice much change in your weight or waist size. Some women begin to experience morning sickness, common between week six all the way until your second trimester. You may also feel more moody and emotional than usual due to the newly fluctuating hormone levels.
Activities this week
- Start making a list of questions for your doctor or midwife
- Gather information on your family medical history to help your doctor determine if there are any genetic abnormalities or chronic conditions to be concerned about
How much caffeine is safe? Because caffeine can cross the placenta and prevent some calcium absorption many doctors recommend regulating and reducing your intake, down to about 300 mg of caffeine a day (about a cup of coffee or tea). For tea lovers trying to concieve, consider consuming less green tea during your first trimester. It decreases the effectiveness of folic acid, vital for preventing neural tube defects in the first month of baby's development. Also, take precautions with some herbal teas; certain ingredients may stimulate the uterus and induce miscarriage. Stick to teas made with ginger, lime blossom, peppermint, roasted barley, rose hips and thyme. Avoid teas made with goldenseal, black or blue cohosh, ephedra, dong quai, feverfew, juniper, pennyroyal, Saint-John's-wort, rosemary or thuja.
