Feeling paranoid.

I'm 35 weeks almost 36. This entire pregnancy has been completely complication free. Baby has been super healthy, measuring spot on every time, good heartbeat, etc. Of course I have been uncomfortable, exhausted, moody, etc. these last few weeks but not suffering any complication or anything. I'm just paranoid that because my pregnancy has been so smooth that something is going to go wrong with labor and delivery. :( It doesn't make any sense I know. Anyone else feel this way?
