QuestionHI THANK YOU FOR ANSWER MY QUESTION ON 24 OCT. BUT HOW ACCURATE ARE EARLY U/S ?
BUT LIKE I STATE IN MY EARLY QUESTION MY LMP WAS APRIL 8 HAD SEX PARTNER 1 ON 12 APRIL AND WENT OFF 13 AND THEN ON APRIL 18,22,24 PARTNER 2.
THE DOCTOR AND U/S TECH BOTH I CONCIEVE AROUND 22 BECAUSE ALL THREE U/S LINE UP WITH MY LAST LMP AND THE MEARSEMENT 2.
WOULD THE U/S PICK UP IF I GOT PREGNANT AROUND THE 12 IF NOT AROUND THE 22 HOW MANY DAYS ARE U/S OFF
I HAD 3 U/S AT 5 ,7 AND 9 WEEKS AND THE U/S TECH SAID THEY LINE UP WITH LMP . THAT A WEEK DIFFERENT WOULD THE BABY BE BIGGER BY A WEEK ? BECAUSE AT MY 5 WEEK 6 DAY IT WAS A EMPTY SAC AND SHE COULD NOT SEE ANYTHING . CAN YOU SEE SOMETHING IF I WAS 6WEEKS 5 DAY? I GUESS WHAT MY MAIN CONCERN IS HOW MANY DAY ACCURATE ARE THEY BY DETERMINE YOUR DUE AND CONCEIVE DAY
AnswerUltrasounds in the first trimester are considered accurate by +/- 3 to 5 days. They are operator dependent, so it is only an estimation and cannot be assumed to be 100% accurate. At 5 weeks 6 days, we could expect to see an empty sac (or just see a yolk sac), would not be concerning, but at 6 weeks and 5 days to see an empty sac would be a bit concerning.
If you need to be 100% sure though, only a paternity test will be able to tell you.
Take care,
Sara
