I will assume you are talking about October 26th 2011. If so, it makes your estimated conception date February 1st 2011. This date could be out by a couple of days though. It should not be used to determine paternity.
Sometime around July 26th
October 18th 2009? Your conception date is roughly between Tuesday January 20th 2009 and Monday January 26th 2009, give or take a few days
The approximate date of conception was September 22nd 2009
The approximate date of conception was July 3rd 2008
The approximate date of conception was July 3rd
The approximate date of conception was September 2nd 2009

october 25th
Do you mean July 20th 2010? If so, your conception date is roughly October 26th, 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.
