Hi my lmp was november 18, i am due august 29th what is my ovulation date range, did i get pregnant from sex nov 29, or sex dec 2nd-dec 6?

Difficult to say: That is a narrow range of dates and fertilization could have occurred at any time during those days.

Hard to say: This is not an exact science, especially working backwards in time. With an LMP of 11/18 anytime in that range you give is possible. I'm curious though: your edd (due date) appears to have been adjusted to august 29, since edd from your LMP would be august 25. If this was done based on early us, it may be the december conception date is more likely.
