What is the conception date if the ultrasound today says the fetus is 12 weeks and 6 days old?
To determine the conception date based on a fetus being 12 weeks and 6 days old, you would subtract that gestational age from today's date. Since gestational age is typically calculated from the first day of the last menstrual period (LMP), you would subtract approximately 13 weeks (or 3 months and 6 days) from today's date to estimate the conception date. This would mean the conception likely occurred around 3 months and 6 days before today.
If an ultrasound showed you were 19 weeks 2 days pregnant can you count back to see when you conceived?
Ultrasound gives an estimate of the age of the foetus. At this stage of the pregnancy, it's quite accurate, but it's still only an estimate, and the date of conception could be a few days, even a week, away from the date 19 weeks and 2 days ago.
When was your estimate conception date if your due date is march 18 2009 but you did not have your period June 11but the doctors say your conception date is June 25th is that the day you had sex?
no June 25th would be the app date the sperm met the egg it can be up to 7 days before this the act of sex that lead to conception so for example if you had sex June 18 through 25 would lead to conception on June 25th. but as far as that not being your last period ultrasounds are better than lmp for timing so u take off two weeks from ur ultrasound and this will tell ur app day of conception if the ultrasound says u are 6 weeks u got pregnant app 4 weeks ago because everything goes by lmp including ultrasound so ultrasounds add on two weeks also
Your girlfriend is pregnant and on the ultrasound said GA edd 19 weeks and 0 days but that would place conception to almost 3 weeks before you had sex what does this mean?
They count the weeks of pregnancy back to the last date of the first day of your menstrual period, not to date of conception. For example, I am considered to be at 15 weeks. The first day of my last period was 11/25/08 and the date of conception was anywhere between 12/9 and 12/16
Would a doctor be able to see a baby during an ultrasound only 4 days after conception?
no
What is the conception date if the ultrasound today says the fetus is 8 weeks and 4 days old?
Count back 2 weeks, so 6 weeks and 4 days old. Count back 6 weeks and 4 days old on a calendar and that would be an estimate. Also, check out www.babymed.com, and put in you're due date or you're last LMP and they can tell you an estimate of conception. God Bless
How would you know if you were pregnant with twins at eight weeks?
The only sure way of knowing you are pregnant with twins is by ultrasound. An ultrasound at 8 weeks would show if you were carrying a multiple pregnancy.
Is an ultrasound scan measured from your last period or when the baby was conceived?
Hi An ultrasound provides a picture of the baby in the womb. The date of conception could be intelligently guessed at by your gynacologist, probably to within a couple of days if not better.AnswerThe date of conception would be calculated by the professional and the length of pregnancy is found by working back two weeks before this.Ultrasounds have only been around for thirty years or so and before that the only way of calculating the length of pregnancy was from the first day of the last period - on average two weeks before conception as we now know.
If your yolk sac was measured on Jan 7th then you could not have fallen pregnant on the 4th of Jan would have to have been befor that?
You are correct. A yolk sac is typically visible on ultrasound around 5-6 weeks of pregnancy, which is dated from the first day of the last menstrual period. Therefore, if the yolk sac was measured on January 7th, conception would have occurred prior to January 4th.
How soon do you miss a period after conception?
You would miss the very next one, which is usually two weeks or so after conception.
My ultrasound puts me at 21 weeks preg that would mean I was feeling movement at 14 weeks took cheap home test at 3 weeks now measure 26CM and not sure of LMP could ultrasound be off by 3 or 4 weeks?
my ultrasound said that my last period was nov25 could it be right
You found out today you were 4 weeks pregnant the nurse at your job gave you an ultrasound said she seend blood around the sack she told you to come get another ultrasound next week what do you think?
Hello, Blood can be difficult to see on a ultrasound. Picture a ultrasound picture, the images are grey and hazy. Also if you are 4 weeks pregnant the pregnancy would not be visible on a ultrasound scan until you were 6 weeks pregnant. The only person who can accurately and thoroughly read a ultrasound is a Radiographer or a Obstetrician Doctor. I would make a appointment with your Doctor, have a pregnancy blood test performed and book a ultrasound scan for 2-3 weeks time. You need a quantitative beta HCG blood test to measure the level of HCG in your blood which will also tell you if your pregnancy is viable. Good luck.
