hey everyone just a quick question, my due date was changed there a last week, origainally it was 28th july, does that mean conception occured in october? its now july 18th which would mean conception def occured in october right???? i was convinced that i had conceived in october as i had sore boobs and was tired  the last week in october and was the first sign for me to do a pregnancy test. just confused about the dating

GRose is right...the best thing to do is stick with the original due date. The further along you get, the less accurate the EDD based on ultrasound is. For example, when I was pg with my son, I was about 7 months along, and the ultrasound said I was a full six weeks further along than I really was. I knew it wasn't possible, because I had ONE conception date to choose from for several months...lol. And this time, my "real" due date is 08/05/09. But at my last ultrasound, they said I was two weeks further along. Again, not possible, because I was tracking ovulation and know when I got pregnant - down to the day and time. LOL. Anyway...were I you, I assume to original date is the "right" one. That way you won't start panicking that you're "overdue" at the end, when you really aren't!

no i def know who the father is, just curious thats all about dates and scans

Did your dr base your first due date off of an early ultrasound (6-8 weeks)? If he did, you base your conception date off of that. Your due date may have changed now just because your baby seems to be growing at a different rate. Early u/s are very accurate and are usually only off by a few days if any.
If you are trying to figure out who the father may be than your best bet is a DNA test but you could talk to your doctor about when he thinks you conceived, he would have the best answer for you.
Good Luck!

Personally, I am not sure how exact the dates can be since all babies do grow at different rates.  If your date changed from that much, it may change enough.  I guess this really isn't much insight LOL!  Just my opinion!
