Can i have tetanus??

So 24 hours ago i poked my forehead with a rusty nail doing some work in the shed. It barley punctured the skin. I put a piece of toilet paper over where it hit and there was the tiniest little pink spot smaller than a grain of salt. but there was still some blood there never the less. i highly doubt I've had my tetanus shot in the last 10 years. Do i have to go and get a tetanus shot now?? or is it to late?? what should i do?

I'd go get one.  Whether or not you need it from this incident, it is a good thing to have backing you up for the next time you do some work in the shed.
