yes ofcourse it will be unsafe if u do not return tomorrow. by the way this combination of mifepristone and misoprostol
is allowed to be given only till 7 to 9 weeks of pregnancy
. im shocked at this treatment that you have received.!!! anyhow please go tomorrow as yur doc has called you else the complete foetus will not be aborted and there will be chances of incomplete abortin which is something even more dangerous that the unheard of , strange treatment you have received.
