Hi, I went to my doctor today and found out that I am pregnant. The first day of my last menstrual period was 9th Nov,2007. The length of my cycle was 28 days last year, but this year it somehow ranges from 32-35 and back to 28 days on October and November.My doctor said that my due date is 7th July,2008. What I don't understand is that when I use the pregnancy due date calculators on the internet all of it says my due date is 15th August,2008. Which one is correct??

Oops, post it on the wrong topic. Please disregard

I don't understand either. According to Nagele's Rule, you should be due on August 16.

Nagele's Rule says that you subtract 3 months and add 7 days to your last menstrual period. If your doctor has a different date, almost a month earlier, you should ask him/her how they formulated this due date.

I will do that. My first prenatal visit will be with ob-gyn that's on 2nd January. Im sure they'll gigure it out. Thanks for the reply.

That's definitely wrong my baby is due the 7th July 08 and my lmp was 25th sept
