The only way to be able to reallly tell is to get a dna test done

Ok I had sex on the 8 of december so if the doctor measures the baby through and ultrasound and tells me I am 7 wks and 2 days as of friday that just passed and I concieved on december 8th is he making a guess or is he rigth

It's possible they aren't right. Miscalculations can happen sometimes...

Well I had a weird period ( a couple of days) in november and did not have one in december. So if I had my weird period beginning november 24, and you count 14 days later is that your concievement day or just a calculation and can they determine how far along you are when they do a blood test
