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.

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

How can I tell if the two ovarian masses that were discovered in a transvaginal ultrasound are malignant?

You can't: Most commonly, if ovarian masses are discovered on ultrasound, they are followed at 2-3 month intervals. If they grow over time, your gyn may consider removing them.

May be more aggressive in removing the ovary. ...Read more
