20 Weeks and No Heartbeat

I’m 20 weeks today . Went for my test and ADC doctor said there isn’t any heartbeat . 19th June, I have any appointments check and all good . Baby growing well . I have no bleeding or cramp or pain . Doctor give me 2 options. 1st is to take pills to remove the baby . 2nd is wait next week, see if any change. I choose second option . Anyone have faced this issue too ?
