Am due on 12th and the spin thingie says am due on March 12 since my last menstrual cycle was June 5th and ultrasound says am due on 3/13/15
At one of my Dr appts, my bf got one of the little spin wheels that tell you everything by your due date. It says if your due date is March 11 your probable day of conception is June 18 & the first date of your last menstrual cycle was June 4.
My lmp was may 28th, conceived june 11th, due date march 4th
I'm due March 10 and my date was June 6 I believe
I'd say you conceived sometime in June. I'm due the 17th and my LMP was June 10th.
I'm also due then. 9th June was the start of my last menstrual cycle. :)
