I am not sure when we conceived, but I think it was around the 12th, so that would make sense that you'd be 5 weeks. My LMP was on the 30th of January. I am 5 weeks and 2 days. So that would mean your due date would be around the 8th of January, but ask your doctor. I calculated my due date using different book calendars, and formulas. I came up with the 6th based on my LMP.
I haven't asked my exact due date yet but I think it is around that time. Do you know what day you conceived? I conceived on Feb. 14th. I am trying to figure out what my due date would be. I am 5 weeks today(I think)
