Kristy Lee - I too have had a m/c and I have had 4-5 episodes of bleeding / spotting in this preg - it has varied b/w dark brown blood to red blood.
I cant say for certain that eveything is ok or not - but take it form me - you can have some bleeding and still go on to be ok. I know tho how scarey it is after a m/c.
Keeping my fingers crossed for you!!
Love
kate
