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.
Answer
The 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.

Is it possible to have a heavy period or bleeding while pregnant?
yes it is possible to have heavy period or bleeding while pregnant. i am a witness to this myself. i took a pregnancy test on october 30th. i got a positive result. but two weeks prior to this i had a period. i also had a heavy regular period in sept. and in aug. i was told that my exp. due date would be July 25 2010. i went for my prenatal visit yesterday and there was heavy bleeding. so my doc sent me to ultrasound to see what was going on. they did the ultrasound and the baby was fine! but i told the lady that was doing the ultrasound that the baby was a little big for 5 wks. she said oh no this baby is 10 wks and 1 day. so that changed my due date to may 25 2010. so i had been pregnant and had 2 periods even after i conceived.
How can you be 5 weeks and 3 days pregnant on May 28 if the baby was conceived on May 3?
You can't. Either you got pregnant after having had sex earlier, or the ultrasound operator is wrong.
First Ultrasound was at 15 weeks 0 days Baby measured 15 weeks 2nd Ultrasound was at 17 weeks 0 days baby measured 17 weeks 4 days and doctor is very concerned Why?
There is a possibility she will have a big baby. I wouldn't worry about it too much. I bet another ultrasound has been booked that will be fine. I was induced at 36 weeks becasue Twin 2 wasn't growing. Twin 1 weighed 4lb 15ounces, Twin 2 weighed 6 lb 3ounces!!
You slept with someone on April 11th and on April 15 took a pregnancy test and it was positive April 24th you had an ultrasound and you were 6wks So doesnt this mean you conceived in march?
Yes. Your baby was on his/her way before April 11. If you're 6 weeks pregnant, you conceived around 4 wks ago (doctors start counting weeks from your last period). BUT it still isn't April 24...
At 18 and a half weeks pregnant can an ultrasound read at 20 weeks what would be the reason Is the baby big can an ultrasound be off by 10 days?
At this stage, yes the ultrasound can be off by 10 days. Mine was off by ten days the other way, that is I thought I was 18 weeks and the ultrasound said 16 and a half. I knew when I had conceived because my husband had been away on a trip.
Can you be pregnant and lose the baby and not know that you loss the baby and your period comes on regularly?
Yes of course you can... many babies are conceived before a period has even been missed and just stops developing after a few days.
If your last period was may 20th and your baby was born on march 12th what day did you get pregnant?
middle of June would be when the baby is conceived
