Thank you for your query.
Sometimes there is a kind of abortion which is called a missed abortion
Herein the growing fetus fails to develop normally and there is no cramps or pain or heavy bleeding, but the growth stops and hence pregnancy
has to be terminated.
At 7 weeks, the fetus alongwith heartbeat should be seen.
Please ensure you are having a transvaginal ultrasound
, as abdominal scan would fail to be reliable.
Sometimes rarely if there is delayed ovulation or delayed periods, a late conception can occur.
Best is to wait for a week and still if there is no growth, then go for termination.
Meanwhile, take rest, avoid exertion stress
and coitus, and take supplements as advised.
