How to stop worrying

So I know this is dumb of me to admit. But I was really young. So about 3 1/2 years ago I went to a lady to read my tarot cards. Most of the things she predicted became reality. Like me getting an infection on my wisdom tooth and having a crazy psycho ex. Well that being said she also predicted that I would lose my first pregnancy. I just found out I’m pregnant on thanksgiving day and I’m truly always worried if it will go wrong because I keep thinking of what she told me. I pray a lot and ask to please not let that become a reality. What else can I do?
