nowadays i am interested in my natal reading and trying to understand it on my own. But issue is that when i am entering my personal data on various astrology sites, the planets or signs can be different in some houses. For example i would like to understand more about 7th house of personal relations and marriage, would like to see more about spouse character etc. but the planets little bit differ, Sun, Venus, Mercury, then Sun, Venus, Rahu, Mercury or even with Pluto in 7th house to name as example, therefore the readings are different. How to find out the accuracy of own natal chart?
