I know i should not be paranoid but...

I had an interview last week, overall I do feel ur went smoothly but one point I was explaining about an unexpected situation & I accidentally said the phrase 'oh crap' but with the situation it was in context. Although this position is a temp position the interviewer did ask if I wanted to this kind of job long term I said yes & gave my reason why. When she asked when can I start I said pretty much immediately but mentioned a doctor appointment I had, but paranoid she thinks I'm ill but I am not! I shld know 2moro outcome of decision but do u think I messed up by saying oh crap & by mentioning my doctor appointment?
