It is normal that the gestational sac cannot be detected after 48 days of pregnancy. Although most of them are 50 days, some of them are not obvious. Because pregnant mothers have a long menstrual cycle, or ovulation is late at that time, it can't be detected for the time being. It is recommended to go to the hospital for a B-ultrasound reexamination in two weeks. Most of them can be queried again.
Time is too short. If the pregnant mother has no special circumstances, the pregnant mother can go to the hospital for examination two months later. Of course, it is still too early to draw conclusions.
At 40 days, if you do B-ultrasound, you can't see the gestational sac, but the pregnancy time is relatively short, so you can go to the hospital for another week.
At present, the pregnancy time is still relatively short, and it is not yet possible to diagnose whether there is abnormality. At this time, HCG and progesterone in blood can be detected as a reference. If the value is low, you can consider abortion treatment. Check again after 2 weeks, pay attention to rest, don't use drugs indiscriminately, and have abdominal pain or bleeding symptoms during the period. Consider seeing an obstetrician in time.
