Best advice is to get yourself tested - you are in a good time frame for all STI's you were at risk from. Take some comfort from Vance, this was low risk and no symptoms is a good sign. Get yourself tested asap. You cant infect your wife with something you dont have. If you are positive for anything (very unlikely) then informing your partner is a must so she can be treated. All the best.
Yes it is possible, with no symptoms from you the chance is not that great, but still possible.
