for those who had a subchronic hemmorage in the second trimester

Has anyone has a SCH in their second trimester? How was your bleeding? Only asking because I have one, i had a small amount of brown blood and they said "its big enough where we expect for you to have been bleeding in large amounts." 
But i didnt. I barely bled at all, maybe a few spots and it was always brown. 2 weeks later, and the past 2 nights while sleeping ive woken up to my pants ans underwear being soaked with blood (brown blood again)
So im wondering for those who have had it, what it meant for you.
