I think if you just try and get as much rest as possible for a few days you should be ok. I notice if I am tired/sick/stressed that it can feel like my supply has dropped - and I believe it does impact on it, but I've read if you eat well, get plenty of sleep/rest and feed your baby often then it should be ok.
Hope you are feeling better!
