I bled too during my 6th week. Went to public hospital, they didnt prescribe me with any medication. I eventually seek 2nd opinion with a private gynae and he prescribed me with duphaston. So far, it has helped me and I have stopped bleeding completely. What I may suggest is, ask your gynae about this medication. I think it would really help you :)
There is a pill that the Gynae can give to “secure” the pregnancy. Call to check.
it might be spotting.. Best to consult the gynae immediately.
