There are many articles published on the Internet about early pregnancy signs, but they are not usually very specific or based on actual data. FertilityFriend.com's Early Pregnancy Signs Estimator allows you to go beyond rumors and myths and explore real data. The Early Pregnancy Signs Estimator does this. It is an interactive way for you to directly explore your own signs and compare them to the community data. As a member of the leading fertility charting site you have unparalleled access to the very data of interest.
The Early Pregnancy Signs Estimator is a search tool which complements FertilityFriend.com's Chart Gallery.
It allows you to search charts in the gallery based on symptoms and Days Past Ovulation (DPO) criteria. The results are presented as simple gauges displaying the relative probabilities between pregnancy, ovulatory and miscarriages categories:
For example, the graph for Ovulatory versus Pregnancy shows the
difference between the probability of the occurrence of your criteria in
the pregnancy and ovulatory categories respectively.
If the needle is on 50% it means that there is no difference of probability of occurrence within the two categories. Your criteria occur with equal frequency in both categories.
If the needle is on 70% it means that the probability of finding your criteria is 20% more (70% minus 50%)� in the Pregnancy category than in the Ovulatory category.
If the needle is on 30% it means that the probability of finding your criteria is 20% less (50% minus 30%) in the Pregnancy category than in the Ovulatory category.
Why does it not search for all the symptoms on my charts?
Although the tool lets you display your own charts for reference, searching the gallery to match exactly all your symptoms would not return enough results to display any significant statistical information. If you are interested in gauging the early pregnancy symptoms using all the signs on your chart, please refer to the Early Pregnancy Signs Analyzer which uses mathematical modeling techniques to estimate a global probability.
How accurate is it?
The most important point to remember is that the most accurate proof of pregnancy is the actual pregnancy test. There is really no way around this. The purpose of this tool is to let you gauge your symptoms against what the community has recorded. Given the size and diversity of the sample available the results have their own significance. Your mileage may vary though. As for all statistical prediction, it is certainly something you can consider as an additional clue and not as a definite answer.
