Tarot Cards

I did not really know where to post this so hope this is not the wrong place :/ Anyways, today I did a few online tarot card readings and the cards said terrible things. They mentioned things like death and betrayal several times. This wouldn't have freaked me out to much but I'm pregnant and the death thing makes me really nervous. I'm also married and several times it mentioned things about a lovers betrayal which also freaked me out. I know some might not consider tarot card readings as an accurate prediction of the future but I was wondering if anyone did believe in tarot cards and if anyone had the things the tarot card foretold come true. I just feel really uneasy now after the readings...
