Not really any time frame other then like a day or two at most for some STD's.
thank you for your response - I am fortunate enough to just had a talk with my wife to go off birth control for a while and we would use a condom in the interem, due to side effects from the birth control. I love my wife and family enough not to want to ruin this over a stupid mistake. We talked many years ago about if one of ever did have sex and it was a mistake, not an ongoing affair, that neither of us would want to know about it, and I want to hold onto that.
I did want to know though, that if you do contract an STD, is there a period of time before you would be considered contagious and could pass it on? Do they need an incubation period of time?
No there is not.
Also to be honest, your spouse is going to get a little suspicious that you are avoiding sex for 3 months. Might want to 'fess up to what's been going on so that you two can work thru this together.

Is there anything that can be done, hours, or days after possible exposure to limit your chances of any type of infection? Boost immune system etc?
You already posted in the hiv forum and they'll address that part with you.
as for other std's, you need to get a full std screening done. You can get tested for chlamydia and gonorrhea 2 weeks post encounter, syphilis anytime after 6 weeks and hiv and herpes anytime after 3 months.
