Is this normal?

Is it normal to be scared of pregnancy because of the symptoms? I'm not sure if because i see how a lot of girls talk bad about the symptoms but that's my biggest fear & I'm not sure if it's normal? Idk how bad they actually are but i feel like I'm not mentally strong to deal with them & my biggest fear is to not be able to overcome that fear... mostly to be so nauseous I'm gonna have to quit my job & just avoid every place so I'm gonna have to be in bed until it passes, if it does
