Neither the creators of the Lunar Conception Calculator nor the owners of the website are medical professionals, so if you'll decide to use the results of this calculation in any way, you will do that at your own risk.

Risk Factor

Please note that for some women conception on one of the dates defined by the Calculator can result in miscarriage or abnormal birth. No calculator can take into account all the complex factors that can be in play in different cases.

You can now offer a personal consultation with our specialist, which is especially recommended in complex cases.
