Brown bleeding during week 4 and 5

I went to the A&E When I had brown discharge and was given duphaston. Then I went to my private gynae a couple of days ago and he discovered a hematoma actually! And gave me duphaston to continue and a progesterone shot, and I was advised not to walk/stand so much for 2 weeks. Most of the time it’s fine, don’t want to worry you! But do monitor and also stand and walk less first
