Is it normal?

I'm very afraid of becoming pregnant because of the symptoms. I don't feel strong enough to cope with them, & it might be something irrational since theres so many people in this world. I know that some women wouldn't hesitate on dealing with the symptoms just to carry their own baby. I guess my fear for symptoms is bigger than knowing how lucky i am but the hard thing is that i don't know how to deal with it mentally & it sucks..
