The earliest scans are the most accurate, since the baby's development follows a very specific pattern in the first trimester. I would go by your earliest scan...a few days either way doesn't make a difference. If during the second and third trimester the baby measures differently, it usually means they're growing fast or slow, not that the conception date is different. That's why some babies come out 6 pounds and some come out 9 pounds, except for the first trimester they grow at different rates.
A paternity test is a test of the baby's DNA to see who the father is. They usually do it after the baby is born, though it is possible to do it in the womb.
If they tell you that you're 15 weeks or more, then you're more. It doesn't make a difference either way, except that you would need a paternity test. I also did not say you were 9 weeks. If you read it I said that you were NOT almost 9 weeks, because you weren't. There's always the possibility of it being wrong, but it's very doubtful.
I didnt say I was 9 weeks I said would I of been almost! Coz they put 2 weeks on because of your last period.. But I ain't had a period since 27th August. I had a spot of blood the 4th October so I cant really tell.. But when I had my scan they measured the baby and told me what I was...
Could they be wrong? And I be more weeks pregnant?
No I said what If they tell me I am 15 weeks... What If they tell me I'm more? Can they do that even though my last scan they told me I was 10 weeks 6 days.. I am 12 weeks today and for my scan on Monday! Well my dating scan! I'm just a lil worried. Whose do you think this is?!
Sperm can survive for up to a week in the female body under perfect conditions. I'm not sure how you're getting that you conceived 2 weeks earlier if you're 12 weeks today. When you had the scan and it said you were 10 weeks 6 days, that's how far you were. You weren't almost 9 weeks, you were almost 11 weeks. Dating scans such as those show the weeks you currently are. I'm also not understanding how you're getting that they would tell you that you're 15 weeks on Monday. If you were 12 weeks today, at the scan you would be 12 weeks 6 days.
