Should i be worried?

So for the last couple months my period has been coming extremely late and it only lasts a couple days when usually it last a full week and its very light. I am not on birth control and I haven't been since October last year and its late by 1 day so far this month. Idk what it means and I dont wanna google it cause google doesn't give correct answers. I've been leaning to have a kid for years and it'll be just wonderful if I was in fact pregnant. Any ideas? Anyone else experiencing this??
