The easy answer to this is "No". We purposefully do not place lava beads on fertility and pregnancy bracelets for this reason. While data on essential oils have expanded in the past ten years, its still in the early stages. Scientific evidence suggests that some essential oils, for example, can cause early contractions. We do not recommend taking these risks if you are trying to conceive, pregnant or under the care of a doctor. If you would like to use essential oils, contact your physician first and have this discussion with your physician. Again, we do not advise, not recommend, the use of essential oil when pregnant, trying to conceive, or under the care of a physician.
