∙ 2007-01-14 09:26:24At 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.
There is no way to pinpoint that exactly from an ultrasound done after the first six to twelve weeks. 3rd trimester ultrasounds are notoriously unreliable for measuring the size and age of the fetus. Your last menstrual period was likely in the first half of September. Conception was likely to be late September or early October.
You conceived 4 and 1/2 weeks before you wrote this question. Check your calendar to see the exact date.
i would say no
I don't think you can tell when you conceived from a single HCG test as the normal variation is so wide so the test cannot say definitively you are 5 and one half weeks pregnant. It is much more accurate to have an ultrasound scan and measure the size of the baby. Even then you may be out by 2-3 days either way.
it means it's a boy
6 and a half weeks.
There are 26 weeks in half a year.

You would of just conceived in the last 3-6 days. If you are truly 5 and a half weeks pregnant you would have conceived around 18th June, but there is a wide variation in 'normal' HCG levels so an ultrasound scan can give you a more accurate date. Incidentally, here in Britain very few women have HCG levels done. I have been a midwife since 1979 and at no time over the past 26 years has it been done routinely.
348 weeks in 4 and a half years.
26 weeks, Because there are 7 weeks.
