Ok in 7 week what is mean as week 1

From scan report on oct 28 it show 7 weeks 2 day<br> From sep 7 to oct 28 it became 7 week 2 day .that's means September mid I got pregnant

No body can say wen exactly someone got pregnant, 7weeks means it's 7weeks. Please don't complicate calculations.

From scan how can I find when did I actually get ppregnant.Because October 28 ultrasounds show 7 week 2 day .from back count from oct 28 it shows sep 7 as first day and also due date i subtract 280 days from june 13 it also get sep 7.<br> That's means after sep 7 i got pregnant

Scan will show you the precise date based on the development of the baby...That is infact more accurate than edd
