MY LAST LMP WAS 8/27 MY CONCEPTION DATE IS 9/7/-9/10.Y DUE DATE IS 6/3. I DON'T UNDERSTAND HOW YOU DUE DATE WOULD BE SO FAR OFF FROM MINE. WERE YOUT TTC. I WAS AND KEPT EXACT DATES OF EVERYTHING.
My LMP was on 8/27 and my due date is 6/12. I used the ovulation kit and saw that I was ovulating on day 10 and then around day 22 in my cycle I noticed the usual symptoms of ovulation so I took a few more ovulation tests and saw that I was ovulating again. My due date corresponds pretty much exactly with that second ovulation and my early u/s at 6 weeks, 11 weeks and 13 weeks all correspond with it as well (as well as my 20 wk u/s). So, possibly, you may have ovulated a few weeks after that bleeding incident. Just a thought.... Anyways..congratulations!
Personally I haven't. I'm due on the 16th June. my LMP was September 10th and I have (had) a 26 day cycle. I asked my midwife about the due dates adn she just told me, you're baby will come when it needs to, which I found to make sense!!
I would go by with what your Doc is calculating. Perhaps when you have an ultrasound later and they measure the femur length, they will give you a new date, which they do in most cases.
