hey if he pulle dout in time chances r good in ur favor. but whatevr u do do not stress. stressing prolongs u r epiod which will only make u freak out more so jus ta ke it calm ok. and deal with it as it comes but really shouldnt get all werked up if he pulled out. good luck

I'd say you should be ok, but I suggest if you're two days late (I'm guessing you'll be worrying like hell by then) get a pregnancy test anyway.
At least if you know sooner (although, I say again, I'm sure you'll be ok), you'll have more options.
