how far along/when am i due?

so i know that they calculate how far along you are based on your LMP, but what if your cycle is a bit longer than 28 days?

my LMP was august 26

i ovulated around september 14 (pretty sure it was that day) (CD22)

working off of when i ovulated i should have been due on september 28th (CD 36)

if i go from my LMP that would put me at about 5 weeks (i think) but if i work off of a typical 28 day cycle and calculate from 2 weeks before i ovulated then i'm 4 weeks. which one is it? i spoke to the dr today and completely forgot to ask...

also, it seems to me like either of the above would put my due date somewhere in the first week/beginning of june. is that correct?

thanks in advance!

Re: how far along/when am i due?

you can do this based on conception date-- plug in when you think you O'd for something a little more accurate than LMP for your cycle.
