Bad SCH bleed

Justine
I just had another bad SCH bleed. 
Anyone else with a SCH - have you ever had a gush of blood that went through your pants and onto your seat? This time mine was brown - I think that means it's possibly resolving? It has been several weeks since my last bleed so I'm not really sure what to think. I'm still having some lower back pain so I'm not sure if I should be concerned. 
Anyone gone through it and have any advice ?
