I add a half teaspoon of eggshell powder to my smoothies ever morning. I have no plans to stop, as I am clear that the eggshells help strengthen my existing teeth. I purchased dried comfrey root at the health food store. I added two tablespoons to a quart of water and, after bringing it to a boil, let it simmer for half an hour. I then strained the tea, and transferred it to a large container, which I kept in the refrigerator.
When can I start using a fetal doppler? In some woman the fetal heart can be detected as early as 8-12 weeks. The fetal heartbeat should be audible 95% of the time in 12-week pregnancies, and nearly 100% of the time after 14 weeks. Earlier in pregnancy, between 8-12 weeks, your success in finding the heart rate can have to do with the quality of your device.
When using your fetal doppler it is suggested that you use it in short intervals, infrequently, and following the first trimester. As a general rule an exam with a fetal doppler should never last longer than 10 minutes. If you don't find the heartbeat in this period of time, take a break.
