Anyone else bleed/spot throughout their entire pregnancy?

I'm 16w and have had bleeding/spotting off and on the entire time. I had a small SCH that was identified at 5w and resolved at 8w. I had spotting after the SCH resolved and found that I had a friable cervix. Now the friable cervix is resolved but I'm still spotting!  Baby looks great and heartbeat is also great. OB is confident that the blood is from the cervix and not the uterus or baby. Am I doomed to spot the entire pregnancy?  Any tips on how to cope?
