33 weeks and every single day when I wipe I have blood.

I'm 33 weeks and I wipe and always have brown or pink blood at least one time a day, and sometimes I have red clumps mixed in with the brown or pink blood. The brown/pink will also be in my underwear. It isn't every time every day, but at least like once a day and has happened for over a week. I DID mention it to my doctor, but he didn't say anything about it, and just told me I didn't have blood in my urine at that visit. Also, I have it daily regardless of whether or not I've had sex that day or if I've not had sex for two weeks. My doctor checked my cervix for dialation but I wasn't dialated any and he still never said anything about the blood. Anyone know anything?
