A member asked:

Lmp was 4-27. i was given 2 due dates...2/17 on june 23 & 2/5 given on 8/12. what is my likely conception date range? late ovulation?

By dates 5/2: I am not sure what the 1st due date was based on because by your dates (LMP) you would be due on 2/5 or 2/6. If the 1st due date was based on an ultrasound it is very reliable that early.Conception probably occured between 5/6 and 5/17.
