May 13th 2010? Your conception date is roughly between Saturday August 15th 2009 and Friday August 21st 2009, give or take a few days
Sept 13
The approximate date of conception was October 20th
The approximate date of conception was June 20th
17th-25th November.
The approximate date of conception was September 13 2005.
It depends on whether May 13th was your due date or not. If it was your due date, this makes your estimated date of conception August 19th 2009. However, this date is give or take a few days. It should not be used to determine paternity either.
If your last menstrual period was May 13, your ovulation should have been approximately between May 26 and May 28, which is when you likely would have conceived.
I would say date of conception was August 12, 13, or 14.
Based on a normal gestation period of 40 weeks the conception date was November 20th.
Sometime in September.
Roughly May 22nd 2009, give or take a few days. However, it is difficult to accurately say when a conception date is. Therefore, I suggest talking to your doctor, midwife or obstetrician about it.
