I went to http://www.intmed.mcw.edu/clincalc/pregnancy.html and put in a due date of Sept 18,2007 and it shows conception date of Dec. 26, 2006. Remember that is based on a 28 day cycle so add or subtract days depending on how long your cycle is. Also, sperm can live in a womans body for 3-5 days, so it can be from sperm from days before that. congrats on the pregnancy =) The answer to this question is simple... If the doctors set it then there is no real way of knowing you would just know the general month which would be December of 2006.
The approximate date of conception was April 27th
Sometime around July 26th
June 18 2006
The estimated date of birth is November 11th
Two weeks after your start of menses in June 2008
Based on a normal gestation period of 40 weeks the conception date was August 25th.
December 26
The approximate date of conception was June 23rd 2009. The start date of your last menstrual period is estimated at June 9th 2009
Sometime around Late August-September.
The conception day would be 11/18/2008, based on you're due date. You're due date is more accurate in the early stages of pregnancy. SO if you got an ultrasound in you're first 12 weeks, it is pretty accurate. Good luck sweetey!
Her due date is June 18, but she may not calve until after or before then.
October 18th 2009? Your conception date is roughly between Tuesday January 20th 2009 and Monday January 26th 2009, give or take a few days
