pregnancy

April 10, 2008

i had an ultrasound on feb 18 and they told me i was 7 weeks and 1 day and that my due date was oct 5. so i got pregnant around jan 11 right. well people say that an ultrasound can be off anywhere between 7 to 14 days depending on when you had it done. would it be off up to 14 days at 7 weeks?

7 W 1 day as per the U/S is from ur Last menstural period. U could have ovulated around Jan 11-15. If they saw a fetal pole, heart beat and gave ur due date based on that, the it cant be off by 2 weeks. Max 3-4 days.

im asking because i had intercorse on dec.19 and took plan b the morning of dec.21 which was long before 48 hours bc i know you only have 72 hours to take it and i started my period dec.22 and it was for like 5 or 6 days. after that i had intercourse again and all through jan and i took a preg test on jan 23 just to see if i could find out if i was preg or not and the lines were very very light. going off of the 1st day of my last period i was due sept.28 but going by the ultrasound i am due oct.5 and i guess its bc i took plan b and it made me ovulate a little late but i did get my period on the day i expected it in dec. so could i still have gotten preg on dec.19 and the ultrasound feb.18 that said im 7 weeks and 1 day be off that far back?

Correct HopeN and Thanks as it's explained this way, and pregnancies can only be precisely upto two weeks off only if ultrasound is done in the second trimester

oh ok so there is no way i got pregnant on dec 19 since my ultrasound on feb.18 said i was 7 weeks and 1 day? i just worry so much because im so excited and my bf is too and i know i messed up and im scared of when i have the baby maybe it wouldnt be his and everything would be ruined. i will never make the same mistake again and i hope other females who see this will learn from my mistake. its not anything anyone would want to be worried about day in and day out. i waake up thinking about it and go to sleep at night thinking about it. its awful. but i was just scared that since you are in your first trimeseter up until 12 or 13 weeks that the baby wouldnt have that much difference in size at 7 weeks and a baby at 9 or 10 weeks. i thought maybe they all were about the same size during the first trimester and didnt get that much bigger until a little later and the ultrasound could be off up to 2 or 3 weeks. im sorry i sound so freaked out about it. im just so scared of what it could be because i know i took plan b and started my period on about the same day i would have maybe a day or 2 early but i was thinking maybe i had a fake period in dec from the plan b and was pregnant and didnt know it
