I'm not sure on your due date, but I also had a short period, lasting a day or two, about 3 weeks after I conceived. You can still have a period after conception, and also when the egg attaches to the uterine wall there is usually a little spotting of blood then too. So you could have even conceived on that first date, but have an o.b. do another ultrasound, that can help confirm the date.

Are u trying to figure out whate date it is bc ur unsure of who the father is bc otherwise I don't think it really matters.. The baby will come when it's ready...  U can deliver anywhere between 37-42 weeks so it could b begining of April or mid may when u actually delivery.. Ur due date is just an estimation of when u could deliever and honestly I've never met anyone to deliver on there due date..

thanks for your thoughts people i thought i would add a bit more info

on my ultrasound at 7.5 weeks i gave my LMP of 18th July
on my ultrasound at 9.5 weeks i didnt give him any info on my last period i said i couldnt remember and he came up with 27th april due date
on my ultrasound at 12 weeks 6 days she had my LMP and she came up with 26th april
due date

so...... using with or without LMP they are very accurate within each other giving my due date  but not accurate to when i had sex which i find confusing !!!

Also my menstral was July 5th which if u go off my menstral my actual due date would b April 11th.. But my doc decided to go off my conception and measurements bc my menstral wasn't all that regular either and with the 16th being the only date possible of conception!!  And all my pregnancies I've conceived on day 5 and day 11 those r the only pregnancies I remember my dates on (my 1st child and my present pregnancy which is my 4th) so my ovulation was preety spread out too.. But it could b likely I suppose for her to have conceived aug 7th but either way her due dates would change..

Ya that would but her menstral wasn't all that regular so I figured go off her measurements and menstral.. So ya it would change her due date a bit but aug 7th just doesn't really add up I don't think that's when she was ovulating so that's y I picked the 24th!
