Just feeling hesitant. Anyone else?

Today we somewhat purchased a crib, changing table, and changing mat for our sweet bundle of joy. A friend was selling it, it's in perfect condition, and we had a good deal! Everything so far with our baby has been WONDERFUL! We've seen the heartbeat 3 times now, finally heard the heartbeat last week for the first time, & we've seen our sweet baby on the ultrasound. I'm now 15w3d and after giving our friend the money I'm just feeling hesitant and anxious still. I just don't like the unexpected. Anyone else feeling this way :( it was just a good deal I could not resist on.
