are pregnancy symptoms the same with every pregnancy

Donna
With my daughter I had no symptoms. I told my friends something wasn't right with my body like I just knew. I wasn't even late and bam bfp after bfp. Now I'm bloated, breasts hurting, hot flashes, and very nauseous, like I can smell any kind of food and feel like I'm gonna throw up. I've got another week till AF so is every pregnancy as far as symptoms different or should they at least be in the same ball park? 
Side note: I feel like I am again, but I'm also scared it's just in my head and it's just me hopeing.
