What’s wrong with two bars on the pregnancy test but no sac on the ultrasound?

Pregnancy test stick two bars for early pregnancy positive, early pregnancy positive but no gestational sac may be physiological phenomenon, ectopic pregnancy or grapes and other reasons, should be further examination, and according to different reasons to take observation and follow-up or surgery and other measures to treat. 1. Physiological phenomenon: regular menstruation, once every 28 days or so, less than 35 days after menopause can be detected by urine with early pregnancy test paper, and the result of conception is positive; however, the appearance of gestational sacs in the uterine cavity should be at least ≥ 35 days after menopause, so the lack of gestational sacs may be caused by ultrasonography too early, and it is recommended that regular rechecks be conducted. 2. Ectopic pregnancy: refers to the fertilized egg is deposited outside the uterine cavity, the gestational sac can not be seen in the uterine cavity, but sometimes in one side of the fallopian tube can be seen in the mass, the disease also has trophoblast formation, can be secretion of HCG, so through the early pregnancy test paper can also be measured positive. Most ectopic pregnancies are treated with surgery, which is determined by the condition and the need for fertility. Conservative surgery can be adopted if the condition is stable and there are reproductive requirements, i.e. retaining the fallopian tube, removing the embryo and then sewing it up, and the surgery can be done under laparoscopy. 3. Grape fetus: due to the trophoblast cells proliferation and secretion of HCG, so the early pregnancy test paper can be measured positive, but it is not a normal pregnancy, so there is no gestational sac in the uterine cavity, but can see the uneven and dense echogenicity. After the diagnosis of gravidarium should go to the regular hospital in time to take the purging surgery treatment.
