Did you have the same pregnancy as your mom?

I don’t know what to expect my mom told me she was sick with my sister the whole entire pregnancy I am now 7 weeks and I have been sick for weeks already and on 3 medicines to control my vomiting. My mom barely had a belly but had complications with my birth and had to have a c section. I am worried about all these things as many people told me you will have the same pregnancy as your mom
