The doctor or ultrasound technician can usually narrow date of conception down to a week by development of the fetus, so if they narrow it down that far for you all you have to do is figure out what day that week you got caught!!! Hope this helps, Good Luck and God Bless!!

If an ultrasound estimates your due date as September 24 what are the chances the conception was on January 13?

It doesn't look that likely. I'm due September 26th and my estimated conception date was January 5th. If the ultrasound is done in early pregnancy (First Trimester) the accuracy of determining a conception date is within 5 days before or after the conception date, so you have a ten day window. Hope this helps!


When an ultrasound gives me an estimated due date do i count back forty weeks to get an estimated conception date?

No, you count back 38 weeks for the conception date, but don't forget this is just an estimate.


If you are 11 weeks pregnant how do you determine the conception date?

Conception date is based on your last ovulation cycle prior to when you didn't get your period. But this can be incorrect if you didn't conceive when you was ovulating. Alternatively you can have a ultrasound scan which will give you a conception date but this can be off by 5 days.

Would excessive drinking the first trimester alter the measurements of ultrasound to determine size and conception date And if so how many days off could it be?

NO ultrasounds measure amniotic fluid and the fetus head, this would not alter you're conception date. If you wanna know you're conception date go to www.webmd.com and they will calculate the time you conceived based on you're due date. It's just an estimate. GOd bless


I dont know when my last lmp was or when the conception occured i know my due date is May 9 2008. I made a mistake and cheated on my husband on August 122007. i need to know exact conception date?

id say in July would be conception cuz if you count from august to may that's ten months!! Id say that conception occured around August 17th. In order to calculate the date of conception, Google 'how to calculate dates of conception' Healthlink is the best site, they allow u to calculate backwards from your due date to conception.


If during a ultrasound the doctor says the baby is 16 weeks along does that mean 16 weeks from conception or Last Menstrual Cycle?

It means from the date of conception.


How can a tell the date of conception?

by the date of ur last period u would typically ovulate two weeks after that one or two weeks before the next one so sex around this date would be u conception date or by an ultrasound u take off two weeks from how many weeks they say u are and that's the possible date of conception because like everything during pregnancy ur ultrasound is measured by lmp.


Is the EDD given to you on your scan date from your LMP or by the date of conception?

EDD is ESTIMATED. If done by scan is 38 weeks from conception. An EDD is based on the LMP (last menstrual period) and not the date of conception. The ultrasound measurements are comparing the baby to the expected size of other babies at the same gestational age. The earlier the ultrasound is done in the pregnancy, the more accurate it will be. Hope this helps! Dr. B.


If you found out your pregnant on April 24your lmp started on March 23 when did you get pregnant?

An ultrasound will determine the date of conception by measuring the fetus. You conceived somewhere between March 23 and April 24. It is difficult to pinpoint the exact date of conception this way without an ultrasound to measure the fetus.

When did you conceive if your ultrasound said you were 12 weeks pregnant on June 25th?

If you gave a due date it might be easier to calculate. Some calculate your due date according to your date your last period started and ended. I'm going to guess that the conception took place sometime around March 26th to April 2nd. But if you gave the due date it would be a little easier.


How do you calculate a date of conception?

Conception usually occurs around the 14th day from the first day of your period. For a current pregnancy, the related link below may be helpful in calculating the approximate date at which conception occurred.


Can one determine the date of conseption closer that two weeks?

I am guessing you mean that you want to know your date of conception? It really depends on a couple of factors. If your normal periods are regular, you can be fairly accurate with conception date within a couple of days. Count back 14 days from when your period was DUE (ie but didn't come because you were pregnant) and this will be around the time of conception. Conception date will be within two days either side of this date. If you are pregnant now, an ultrasound will tell you very accurately what your conception date is. As long as you have an ultrasound within the first 10 weeks - the earlier the better. An experienced ultrasonic person can tell you down to the day - ie six weeks and three days.

Judging by an ultrasound at 8 weeks im due on March 14 which means i concevied on June 21. how accurate is the conception date i was with someone on June 14 and then with someone else the 17-22?

your conception date should be pretty accurate considering u had an ultrasound. you shouldv'e been ovulating around June 21st.
