Hello Nora. How have you been? Hope you're feeling better now.
Anyway, no offense meant but i don't believe in fortune-telling, not even 1%. However, one thing i know is true is that the first 3 months of being pregnant is the most critical phase because anything bad can happen to your baby if you're not careful. Just a small action from you will endanger that small miracle inside your tummy.
So, it's better that you ease your mind, forget about what your mom told you. Rest well, eat healthily and avoid being stressed out because that's harmful to your baby. It is important that you're sleeping well too.
