Pv bleeding in early pregnancy

Renee
Hey girls, I'm around 7weeks pregnant after having miscarried on sep 27th last year at 20weeks and an experiencing Pv bleeding. I had an ultrasound yesterday and saw baby's heart beat etc and was told I have a same heamatoma less then .5ml that would most likely clear up by itself. After having experienced this in my first pregnancy that ended prematurely have any other women experience this also? How long does this bleeding usually last for? Is there anything I should be doing to help this? Any info would be appreciated as I'm calmly feeling like in back to where I started at the potential of miscarrying. 
​Thanks Renee
