serious important question

So 2 years ago I gave birth via vacuum assist because after pushing "in the wrong spot for 2 hours" the baby needed to come out. It was either that or c section. 
I'm wondering what does that even mean? I  didn't get anywhere pushing for 2 hours.. 
Anyways.. I am suppose to give birth in about a month as I'm due with my second child.. I am TERRIFIED of having a c section.. I bled a lot and needed that shot to stop bleeding which I guess is why they wanted to use the vacuum first as a c section would be quite dangerous with increased bleeding risk.
I'm wondering what does pushing in the wrong spot mean I asked and asked and I was doing my best 
Will I be able to push this baby out?
