Late Period

Hey ladies. I recently stopped my birth control about a month ago so this month is my first cycle without it. My body seems to have taken really well go being off it as I've felt slimmer and no more headaches from the pill. My period is due today and I know getting off the pill can throw it off a bit. My question is have any of you gotten pregnant immediately after getting off the pill? I am waiting til after today to test, just to make sure I am infact late. Some of my friends think I am crazy to even entertain the idea lol
