Hi, Recently I Did A Ultrasound, There Have Found A

Hi,
recently I did a ultrasound, there have found a sack but it was 4 week size and after two week again i do ultrasound in there found same size, that means that sack didnt grown up.
now doctor advice me to take isovent & cefotil twice in a day, is this process is okay for my health?
I would like to mention here that i suffered a lot of bleeding before 2nd ultrasound.

is there any possible to do DNC?

Thank you.........
