It means it is approximately four weeks since you conceived, but six weeks since the start of your last period. Pregnancies are dated from the latter date, so you wouldn't say you were four weeks pregnant.
Subtract fourteen weeks (7 days x 14) from the date of the ultrasound.
That means it is the date conceived (or within 48 hours of). It is never right on, but within a week of. Go by what the ultrasound says. No, if your ultrasound says 17 weeks and 2 days that would be that date plus 2 extra weeks, that is around the time of your last period, unless you have irregular periods or conceived straight after a miscarriage or something. The length of pregnancy is always measured from your last period even by ultrasound.
I was told the same thing. Based on my lmp I am 6 weeks but I had an ultrasound done 2 days ago that said I was 4 weeks. I wonder if I am 4 weeks along because that is the time of conception since you dont get pregnant the day of your period. It is usually two weeks later when you ovulate. Let me know if you have heard anything
Gestation is the same as saying pregnant. So when your midwife says that you are at 7 weeks gestation, she is saying you are 7 weeks pregnant. It is most accurate to go from the first day of your last period to figure out how far along you are because babies grow at different paces in the womb and if your baby is growing a little faster at first, the ultrasound may show it as being further along than it really is. Your midwife is probably getting your due date using the last period method, so I would go with her and say that you are 7 weeks pregnant.
Yes, these days the Dr. says 40 weeks and that equals out to be 10 months!
You had a period-looking bleed while pregnant. not that uncommon.
If you know when you conceived you should always go by your date. Ultrasounds, especially later in pregnancy, are not as accurate. Here are the dates that they can be off. The inaccuracy of ultrasound First trimester: 7 days 14 - 20 weeks: 10 days 21 - 30 weeks: 14 days 31 - 42 weeks: 21 days
not really
Guy B's. If the ultrasound said 10 weeks pregnant that means that the embryo is only 8 weeks old. A pregnancy is counted from the first day of your last period. Theoretically, you are considered pregnant roughly two weeks before you even concieve. Hope this helps.
When the doctor counts you as 7 weeks, they are counting from your last period. I figured if the ultrasound says 7 weeks, that is from around sep. 7th, the 1st day of your last period. meaning between sep. 18th thru sep. 24th could have got you pregnant. Likely the 21st. However an ultrasound of 7 weeks on 25th October gives you a due date of 13th June not the 3rd. See the Related Link for "conception-calculator" to the right for more.
You can make an appointment for ultrasound if you want because even if you had a miscarriage the test would show positive since it takes time for the body to settle the hormones. The best thing is to call your doctor on Monday and hear what she says. At 3 weeks and you loose it then, there is nothing they can do.
im exactly the same! im 21 weeks too....i hope someone answers your question.
