Complete placenta previa

25 weeks 4 days and I have complete placenta previa. I haven’t had any red blood episodes just some brown spotting it started Thursday May 23 just brown not a whole lot and not I only really see some slightly light brown tinge or I’ll see it if I have a bowel movement. Baby was checked she is fine and cushion. Just wondering if anyone else has had this? OB is planning on a 37 week c section if it stays this way?
