Can transvaginal ultrasound detect 4 weeks gestation?

Can transvaginal ultrasound detect 4 weeks gestation?

Perhaps: Kyl: at that early stage we may see a decidual (pregnancy) reaction in the uterus and a small gestational sac. We would not be able to see the actual fetal pole or heartbeat that early. A scan at 7-8 weeks would be best to document a good, viable pregnancy with a heartbeat. ...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

Could I have concieved four weeks ago (6 wks gestation) and still not see a gestational sac on transvaginal ultrasound? Also with a beta of 627?

Could I have concieved four weeks ago (6 wks gestation) and still not see a gestational sac on transvaginal ultrasound? Also with a beta of 627?

Yes: If your cycles are irregular, you may be slightly off on dates. A pregnancy should be seen by 5 weeks and a beta of 1000, so I would suggest a followup transvaginal ultrasound a week after the prior one. If no pregnancy is seen at that point, then some concern would arise regarding the viability of your pregnancy. Please follow closely with your OB until the issue is cleared up.

Look harder: It could be intra-Abdominal. It could be what is called a mole. Ultrasound has a poor resolution. It may be so small that you don't see it but you must must continue looking.

I recently had a transvaginal ultrasound done & it said I'm 12 weeks & 5 days is it okay that the baby measures 11.3 cm? Is that too big or too small?

Fine: The ultrasound dating of a pregnancy is based on the fetal measurements so, if the ultrasound dating agrees with your dating based on your last menstrual period, the baby is just the right size. Remember, however, that babies gain most of their weight in the third trimester and that is when you see the greatest difference between large and small babies. Best wishes to you both. ...Read more

I had an early transvaginal ultrasound at 6 weeks 6 days and it matched my LMP to the day. When did I o? And what's the average life of sperm?

Around Day 14: Assuming you have a 28 day cycle, you probably ovulated around day 14 of your cycle (from the first day of your menstrual period). Sperm that make their way into your tubes remain viable about 3-4 days on average and at the outside may last a little longer.

Good luck. ...Read more

I had a transvaginal ultrasound on 11 june 2012. The doctor told me I am 6 weeks 3 d. Based off of this when is my most likely date of conception?

Last Period: In general you due date is based on your period. So is your dating in pregnancy. Unless there is a problem dating your pregnancy, the ultrasound does not change that. An ultrasound can vary from your true pregnancy dating so in order to answer your question the first day of your last period must be known. ...Read more

I had a transvaginal ultrasound on Thursday sep 9 and it said I was 5 weeks are they accurate my last period was August 28 did I conceive around sep18?

Dates right?: I'm assuming you had your U/S Oct 9, not Sept 9. If your LMP was 8/28, you would have conceived around Sept 11 and would be around 6 weeks Oct 9. Ultrasound at 5 weeks is not that accurate because frequently dating is based on a measurement of the gestational sac. 7-9 weeks uses a crown-rump measurement and is much more accurate. Best wishes! ...Read more

20 weeks for gender: Domea: the gender of the baby is usually seen at the time of your full anatomy scan which is 18-20 weeks. Sometimes it can be seen sooner or sometimes the baby's position and other factors keep us from seeing it even when you are at the right gestational age. The heart rate is not a good predictor of the baby's gender. ...Read more

Transvaginal USG: Transvaginal ultrasound is most accurate duringvthe first trimester by 5-7 days. If >than 1 week off then your dating may be off because of ovulation etc. Your period also plays a role in this. If your cycles are irregular then ultrasound dates may be off.
