If your cycles were regular, then this type of report more likely indicates unhealthy pregnancy.
You should get repeat ultrasound
after about 8-10 days to see the growth of pregnancy.
If it is growing,well and good.
If not, it indicates missed miscarriage
Meanwhile, you should continue taking folic acid
and some progesterone
supplementation with your doctor's advise.
Hope this helps.
