use the above pregnancy calculator, there are several other ones out there as well, this one will give you a due date and estimated day of conception as well! Just estimate the FIRST day of your LAST period and put that in the first box (mine was 07/06/2009) and then estimate how many days apart your periods are (mine are roughly 30-32) most are 28 day cycles. The Doctor gave me a due date of Apr 12, 2010, but this is close by telling me Apr 15, 2010. All of the calculators are close but different, but it is only a number because actually only 5% of women give birth on their due dates!!!
Your due date would be 10 April 2009.
Based on a normal gestation period of 40 weeks the due date is Tuesday May 4th 2010.
March 13th 2010? That would make your due date roughly December 18th
Your due date is calculated from the date of your last period, which is information that you supply. Actual date of conception is known only if you know it.
my last menstrual period date is 31 july,2010 tell me my conception date.or chance to stat prenancy
Generally, the expected date of delivery (EDD) is calculated as 40 weeks counting from the woman's last menstrual period (or from the date of conception if known).
Almost 15 weeks
You conceive almost immediately after you have sex.
It depends when the dates from your last period were or when your due date is
Conception dates do not depend on the length of your period. Your due date is based on the first day of your last period. Your baby was actually conceived about 2 weeks later.
My last period was also on that date. I dont yet know if I am pregnant but you would be around 4 weeks pregnant at the moment.
Assuming 10 weeks and 3 days is the time since since your last period, your due date will be at 40 weeks. A simple rule to calculate the estimated date of delivery is to add 9 months 7 days to the date of your last period. Eg. Last period = 14 Jan 2009 Estimated date of delivery = 21 Oct 2009 This is just an estimation. Only 3% of women actually deliver on their due dates without any medical intervention. It's usually a few days to a few weeks earlier or later.
