When 1st trimester ultrasounds date pregnancy how do they base the gestational age? Do they assume conception occured on cd14?

When 1st trimester ultrasounds date pregnancy how do they base the gestational age? Do they assume conception occured on cd14?

US: First trimester ultrasound is based on biometric measurements only, the embryonic crown-rump length, which is extremely reliable when done by a skilled sonographer. No assumptiosn need be made at all. The ega is however reported correctly, by convention, from the first day of a hypotehtical last menstrual period; so in that regard it 'assumes' conception on cd 14. ...Read more

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

With a normal pregnancy, all ultrasounds including ones in the 1st trimester showed LMP 10/15/12. Could conception have occurred after 11/7/12?

With a normal pregnancy, all ultrasounds including ones in the 1st trimester showed LMP 10/15/12. Could conception have occurred after 11/7/12?

Pregnancy sono: If the ultrasounds were done in the first trimester and all confirm the 10/15/12 lmp, then there is little chance that conception occurred after 11/7/12. The first trimester ultrasound is usually sensitive to +/- 3 days. ...Read more

My wife got pregnant, in her ultra-sonogram report says she's 5 , 6 weeks pregnant, so is there a medicine that can help me or abortion is only option?

My wife got pregnant, in her ultra-sonogram report says she's 5 , 6 weeks pregnant, so is there a medicine that can help me or abortion is only option?

Medicine is availabl: Assuming that your wife agrees that termination of pregnancy is apprropriate, medicine can be used to end an early pregnancy without a surgical procedure. She would consult a provider and be given instructions on how to take pills and what to expect then. Birth control thereafter would seem best to avoid repitition. ...Read more

Is it normal not to be able to see the heart beat of your unborn baby when your 6 weeks pregnant, with a vaginal ultra sound?

Is it normal not to be able to see the heart beat of your unborn baby when your 6 weeks pregnant, with a vaginal ultra sound?

Possible: At six weeks gestation a transvaginal ultrasound will show fetal heart motion about 93% to 95% of the time. A recheck in one week will tell for sure if everything is ok or not. ...Read more

Miscarriage...6 weeks pregnant since miscarriage begin my girlfriend has been bleeding for 33 day with sever pain my friend had a miscarriage around 6 weeks pregnant and when they did an ultra sound they saw nothing and her hCG count was not doubling ever

Miscarriage...6 weeks pregnant since miscarriage begin my girlfriend has been bleeding for 33 day with sever pain my friend had a miscarriage around 6 weeks pregnant and when they did an ultra sound they saw nothing and her hCG count was not doubling ever

You : You are correct regarding the d&c. She likely has products of conception still present in the uterus which is causing her bleeding. The D&C (dilatation and curretage) will clean the uterus out and stop the bleeding. If her doctor has "blown it off" then she should seek a second opinion. I hope she is better soon. ...Read more

I am 6 weeks pregnant had an ultra sound yesterday..Baby's heart beat strong and docs says baby's fine...I have bleeding and  endometriosis is this typic?

Common, not typical: Endometriosis is associated with infertility, not miscarriage so much. Bleeding in pregnancy is common and can occur from the very friable cervix or the migration of the placenta. Bleeding without cramping is usually benign. ...Read more

I'm about 6 weeks pregnant, went to ER yesterday because i had some bleeding, pinkish-red....Doc did a sonogram, sac was present but no fetal pole?

I'm about 6 weeks pregnant, went to ER yesterday because i had some bleeding, pinkish-red....Doc did a sonogram, sac was present but no fetal pole?

Maybe normal?: There are specific parameters to judge whether early pregnancy is abnormal. Based on measurements. Unfortunately, dates are not always reliable. I would not expect to see a fetal pole unless sac diameter is at least 16-20mm on transvaginal study (25mm abdominal scan). So if they said it was normal, believe it! ...Read more

I am 6 weeks pregnant. Ultrasound today, yolk sac normal, faint heartbeat. Doctor said gestational sac is small a week behind. Will I miscarry?

Early ultrasound: My guess is that you are going to have a follow up scan as there is no mention of a fetal pole or measurement for dating purposes.? Seeing a heart flicker is a positive sign that should be reassuring. I would simply ask for a follow up exam. ...Read more
