I dont think daddy long legs can bite. Their not suppose to be dangerous at all because of that
I think it may just be a coincidence. I think they do say daddy long legs are poisonous but because they're legs are so long they never really bite cuz they can't reach! Plus if it did bite you I don't think it would cause any reaction that quickly. I recently just started getting bloody noses and they say they are a symptom of pregnancy. Also, the fact that you got so upset and your blood pressure shot up prob made the bloody nose more violent. If you feel really sick or anything else happens I would def go to the dr tomorrow though :)
