I think you are going to have to go with the ultrasound on this one.
If your period has lasted for six weeks, you need to see your doctor as soon as possible.
March 13th 2010? That would make your due date roughly December 18th
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).
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.
Based on a normal gestation period of 40 weeks the due date is Wednesday October 13th 2010.
I have had three children and the period after birth lasted around 3 weeks. If you breast feed your baby you will probably not have another period after this one until you stop breast feeding.
Last weeks Tuesday date was Feb 23 2010.
Your period should las around 5 days to a week. Mine lasted for about 2 weeks and I went to the doctor and I am 12 but he said it was totally normal.
The scan date is from your last period.
