My LMP was September 3rd. If yours was September 1st, wouldn't your due date be June 8th? It would make sense with your ticker, as a June 8th due date would mean you're 4w2d today. Unless you're counting from when you ovulated, but I think most if not all OB's calculate your due date from the last date of your menstrual cycle, which would make you due June 8th. I think you're a couple of days further along than you think!! ;)
