You have to use your last menstrual cycle to calculate your due date.
If you found out you were pregnant a week or two ago, you're more than three weeks pregnant. We'll start there. Conception doesn't generally happen until somewhere around day 11-16 and hcg levels are not high enough for a positive test for a little over a week after that which means the earliest you can find out is just over three weeks - before you even miss a period. The easiest way to determine a due date is to figure from LMP. What was the first day of your last period?
My due date with my last menstruation is not the same that the Dc. Gave me... That's because your last menstruation is not ever gonna give you the correct day!!
So you should go to de ob-g so he can do a sonogram and he can give you the right due date!! And a lot of more info that is gonna be good for you and the father..!!
Well that's certainly an interesting opinion there Maria... since doctors and midwives have been calculating estimated due dates fairly accurately from LMP for several decades now, that is... people who are keeping track of their cycles generally find that dating a pregnancy by LMP is extremely accurate. That's why they still use it. If it didn't work, it wouldn't be the generally accepted formula.
I used a due date prediction chart it went off my last period and it told me May 3rd. When I went into the doctor they also told me May 3rd.
My due date is August 22 had ultrasound today
