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.
Do you mean September 7th 2010? If so, it makes your conception date roughly December 14th, give or take a few days. However, it's difficult to accurately say when a conception date was. Therefore, I suggest you talk to your doctor or midwife about it.
December 2006 to January 2007, if your like me...it could be as early as November 2006 (I carried my son for over 10 months).
Roughly between Friday February 20th 2009 and Thursday February 26th 2009, give or take a few days
Mid January of 2007 maybe early February but 90% January
january, congrats on the pregnancy!
