if you are 23 weeks pregnant , then go back 4 weeks later you should be 27 weeks pregnant. Almost 7 months.
Around 2.5 weeks ago.
You shouldn't be big at all. At five weeks pregnant you have just developed an embryo. An ultrasound typically will not even be able to detect a heartbeat yet.
Subtract fourteen weeks (7 days x 14) from the date of the ultrasound.
You could see a heartbeat if they do a transvaginal 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
You have two due dates...one accourding to your last period and one accourding to the size of the child on the ultrasound...i think the ultrasound one is more accurate
The only sure way of knowing you are pregnant with twins is by ultrasound. An ultrasound at 8 weeks would show if you were carrying a multiple pregnancy.
An ultrasound at 6 weeks should show a fetal heartbeat, if there was a fetal heartbeat you're not miscarrying.. It's probable you estimated your due date wrong.
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
Can a ultrasound be accurate if its saying im now due 3 weeks later then they determined?
Usually a doctor wants to see you for the first ultrasound when you're appr. 10-13 weeks pregnant.
The ultrasound dating has excellent and precise estimation of gestation especially if done in the first trimester (first 12 weeks). After 12 weeks, its accuracy goes down. However, compared to dating according to menstrual cycle, the ultrasound would be more accurate.
