What Are The Effects Of Pause 500 Medicine?

Hi doc, I have had d n c surgery on 1st December coz foetus didn t have the heart beat after 7weeks of pregnancy. There was very slight light pink color bleeding and it got over on 10 day. I started having white discharge and after 3 days I again started having bleeding which is pretty heavy. I am not sure what has caused this as I did some house hold chores on 13 day and some bit of walking since I was feeling all OK. My doc says its normal to have bleeding on and off through out the month and suggest me to take pause500. Could you please advise if this is a normal condition, I am really scared. What is the impact of pause500 on my body?should I take this or let blood come out since there could be some unwanted tissues in my uterous which is supposed to come out. Please advise.
