Confused on my due date?

Question

I am confussed about my due date, my doctor is saying that my due date is on December 18th but I say it is the 14th. According to the pregnancy calculators on the web I am in my 12th week. I am so confused on this whole thing. My first day of my last period was March 11. Help me please. Thanks

Answer 1

Honestly, I have two kids and neither of them came on any of the due dates the doctors or calculators gave me. Your baby will come around anwhere around that date, they are unpredictable to the T. :)

Answer 2

Your Due date would be December 9 if you carry a full 40 weeks pregnancy. It is that way because you count from the 11th, thats the first week and then you are 12 weeks now and next week you will me 13 weeks. Your doctor didn't explain to you that you carry for 40 weeks and that if it's your first one then you would carry longer. But if you want more then what you do is go back 3 months from March which would be December and add 7 days from your ending day. If you started March 11 then it would be December 18th, but if you ended on march 11th then it would be December 4th. But your doctor should explain it to you.

Answer 3

You and the rest of the world. There is no scientific way to absolutely calculate the due date. I don't think doctors know how to predict it perfectly.
It is only an estimate. The baby comes when he/she is ready. Anyway, calculating from the date of the last period cannot be accurate. Think about it, everyone's cycles vary...None of mine came on the absolute date, and they were all healthy and big. Two weeks before or two weeks after was considered normal (in the 70s). So unless you are going to schedule a C-section (I hope you don't have to), there is a 90% chance that the date will be different than predicted.
I wouldn't fret about it. Part of the fun is the excitement of not knowing.
I hope that helps

If your doctor performed an ultrasound on you, he may be correct that your due date is the 18th. Due dates are often calculated by your last menstrual cycle as well as the size of the baby on ultrasound. Given that the dates are only 4 days apart, I wouldn't worry too much about it. When you go for an anatomy scan at 20 weeks, they should be able to tell you more accurately what due date is correct.

Answer 5

According to WebMD you will be due on December 16th. Your due date will likely change once they have done an ultrasound.....and what baby really ever comes on their "due date" anyway. I would just assume that your baby will be born somewhere around the middle of December. For your peace of mind however I would go by the doctors due date because that is what the doctor will base everything off of. Good Luck!

Answer 6

Your doctor may be going by the size and development of your body and the baby. If you only know the date of your last period, it's possible that you didn't ovulate exactly 14 days after your period began as most of the calculators assume. A difference of 4 days either way isn't enough to worry about either way, it's HIGHLY unlikely that your baby will choose to be born on either the dr.'s date or yours. :)

Answer 7

you ought to calculate gestational age an analogous techniques docs do - from the 1st day of your final era. Your due date could be 40 weeks from that day - March 15. because of the way pregnancies are dated, you do no longer truthfully conceive until eventually 2 weeks into your "being pregnant" - meaning that your infant is truthfully approximately 19 weeks previous, even however you're 21 weeks pregnant. you likely conceived someplace around the sixteenth of June. complicated, i comprehend. docs especially use your final era as the thank you to estimate your due date because of the fact maximum women folk do no longer comprehend whilst they could have ovulated. So... you and your doctor are the two appropriate. desire that facilitates =)

Answer 8

Given you have a 28 day cycle, you should be 11 weeks and due on December 16th.

Answer 9

My first initial due date w/ my son was march 12 then after my first ultra sound the dr determined it would be march 17...the ultra sound was more accurate then the internet due date calculators....it ok just go by the one the dr gave you

Answer 10

I would not worry at all about a 4 day discrepancy. I don't even know why the use due dates anymore, they should use something more like a due month, haha. Something like only 5% of women give birth on their actual due date. Don't worry about it.
