Infection level during pregnancy

hey ladies. i don't really have any mummy friends to ask so hoping someone can help me on here, anyway I'm 30 weeks and 4 days today my waters broke (slow leak) at 24 weeks I was admitted for a month then got home with in two weeks I'm back in because of bleeding anyway my Cpr level is high! Yesterday it was 67 and today it's 41 and it's meant to be 15 and below so I'm worried it's doing something to the baby she seems fine on the charts but Cor means infection .. They have checked my urine done swabs bloods and can't find where the infection is but its extremely high so we know there's an infection just don't know where they also can't see why there's always a high amount of blood I'm getting worried that the baby isn't safer inside has anyone had high cpr levels or anything like I have
