The Dr. said I’m due November 11th since my last period began on February 4th. Now, I know for sure that I conceived somewhere between Feb 18 and 25. Will telling them this information cause them to change my due date? Thanks for the help.

@debwrb: A lot of women don’t know when exactly they conceived, so most doctors calculate your due date based on the first day of your last menstrual period so there’s an across-the-board calculation for all women. It’s standard practice. If you knew the actual date you ovulated and put it into an online calculator, you’d get a very similar, if not exact, date.

i’ve heard that most women who track their own due dates are usually more acurate then the Doctor. and i heard also over the weekend from a friend that her doctor wanted to induce her because he thought she was past her due date, but actually she was only a week away from the one she tracked… so she waited and had the baby when SHE thought she would. i dont know if this helps… but i thought it was helpful to me. 🙂
EDited to add: CONGRATS!

@debwrb: I think you should tell them, but they might not change your due date unless the baby is measuring really off. My doctor’s office goes my LMP unless baby’s measurements are more than 9 days off in either direction. I think that’s crazy, but that’s what they told me! According to my doctor, I am due 12/10, but according to my chart and my baby’s measurements, I’m due 12/6.
It seems like a bigger deal in your case because your baby is likely younger than they think. If your LMP was 2/4, your doctor is probably assuming you conceived on the 17th, so your baby is likely 1-8 days younger. That would be important to consider when you go for an u/s.

A November 11th due date is based on you conceiving on around February 19th. They look at your first day of last period as a starting point and base it on a 28 day cycle (which puts you at Feb 18th or 19th). So no they will not change your due date based on this information. They may do an ultrasound to confirm dating, and THAT could wind up changing the date. Hope that helped 🙂

I would share this information with your doctor, but based on your period ovulating 14 days into your cycle sounds like a perfect clockwork cycle. I’m sure your doctor will due an ultrasound too and it will help date the pregnancy. Congratulations

Congrats! I knew that my due date was off, so I let the doc know at my first appointment. He had me go in for an U/S to date the pregnancy. They then changed my due date based on the U/S.

Oh yeah, that’s the other thing, when they do an ultrasound if the baby is measuring too many days off from your original due date they’ll change it then.

I agree with PP about how you ovulated based off your last period. My son was predicuted based off of my last period last year Nov 14th. Boy were they wrong, but that is because he came 7 weeks early! Congrats by the way

Now I wish I would have said something..maybe they would have given me an ultrasound. I still havent had one and I have friends that are as far along as I am and have already had two! 🙁

After I found out I was pregnant I asked for a dating scan, and my doctor was happy to give me one. She went off the date on my scan, which doesn’t line up with when I know baby was conceived- i know baby is just measuring small. I told her and my midwife this, but it’s ‘protocol’ I guess to go by the earliest scan date. There is about a week difference between when I know we conceived and their due date.
But, at the end of the day it doesnt matter because baby will come when she wants to so I don’t pay too much attention to it.
