nesting?

yesterday i felt what i think may have been the 'nesting' instinct. i felt restless and wanted to get EVERYTHING organized as fast as possible. i spent a few hours doing tons of laundry, dishes, vacuuming, cleaning bathrooms, organizing my recycling bin (weird right?), hemming curtains and packing my hospital bag. i was getting ready to go outside and wash my car when i told myself that this was insane. i haven't cleaned my car by hand in years. steve and i take our car through the car wash when it needs to be cleaned, so this was an odd behaviour for sure. i felt unsettled when i sat on the couch. i knew i needed more stuff for my hospital bag and considered running out and buying everything else that i need. i didn't want to just sit and relax, i wanted to get everything ready. then i started thinking, isn't it too early to be 'nesting'? does this mean that the baby might come early? or was it just a one time thing? today i also feel like getting stuff organized. i feel anxious over not having everything perfect. what is this? did any of you have this during pregnancy? maybe it's not even a pregnancy thing. i am often too quick to blame things on pregnancy, maybe it's just a desire for spring cleaning. i kind of want to clean my blinds right now.
