Getting anxious

I am starting to get anxious and worried about our choice to start a family right now. We have been married for 3 years and have a nice home to bring a baby into, but I have all of these what ifs. Are we too young? Can we really afford it? Should have we taken more time for ourselves?

Obviously at 31 weeks I know there is no turning back, and I would not give our baby up for anything, we love him. I am just feeling the pressure and responsibility weighing down on me. Did anyone else feel this way towards the end?
