It depends on when your U/S was done. I had an U/S to date my last pregnancy, because I was not having periods due to birth control. My baby was small for gestational age and so the U/S showed him due later than he actually was. BY over 3 weeks. An ultrasound done before 12 weeks is accurate to within 2 or 3 days. After that it becomes less and less accurate as your pregnancy progresses as obviously some babies grow bigger and faster than others.
i doubt it they are usually pretty spot on
Yes it is still possible but it reduces the chances of it occurring
No, the egg will be to small to detect
It is kind of hard to tell until you get your ultrasound. But you can Google pregnancy calculators and it can help you determine the date of conception by entering in some information (such as when your last period was, possible days of intercourse etc.)
Very unlikely.
Somewhere between 3rd and 9th December 2005.
Ultrasound can visualize fetus inside with no errors.
One can find a conception calculator on the "BabyMed" website. The BabyMed conception calculator and reverse pregnancy due date calculator helps you find the possible conception date retrospectively. Just enter your due date, and the pregnancy conception date calculator will calculate the exact possible dates when you got pregnant.
Diet does not affect the gender of your baby. The gender of your baby is determined at conception (when the sperm fertilizes the egg), although it is several months after conception before and ultrasound can visibly "see" the genitalia of the baby.
Fertilization happens sooner than conception. Conception means 'to get pregnant", so females get pregnant after fertilization.
Possible date of conception, 3rd to 11th October.
