The approximate date of conception was May 25th
Roughly February 21st, 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.
The approximate date of conception was August 22nd
Your due date is an estimate. Consequently, your estimated date of conception is October 15, 2005, based on a gestation period of 9 months.
Sometime around 22nd November 2005, give or take a few days.
On or around Nov 29
December 24th give or take a couple of days.
Gestation is 40 weeks from conception. So if conception took place May 15 2009, the due date will probably be 19 February 2010.
You would have become pregnant 12 to 15 days after your last period. There's no way for us to tell you the exact date.
Pregnancies usually last around 9 months, so it would be January 31st, or around then. It could be around January 15th if you conceived when most think it did happen. However, new research says that a pregnancy can last 15-20 days less than the due date or 15-20 days more. It then makes it very difficult to pinpoint the exact date.
Around 11-15 May
June 15, 2010 falls 120 days after February 15, 2010.
February 15, 1961 fell on a Wednesday.
