I'm anxious!!!!

Last month was the first time I have ever been late on my period and I was only late by one day. Right now I am on what is suppose to be my third day of my cycle and it still has not come. It's weird because I am having very lite cramps as tho it is trying to come but it still hasn't. Usually I cramp very bad the day before and of. Also I am very moist. It is not to the point that I'm leaving puddles but enough to like really notice and constantly feel it! Has this happened to anyone else? If so what happened next?
