My SIL is 4 months preg and has had white blood cell level checked. Apparently the count should be between 4 and 11 and her result was 16 a month ago and gone up to 17 now. Docs said they not sure why and its not harming the baby, but they need to treat her with anti-biotics but cant until they know the reason her count is so high.Anyone got any experience or advice on this one? thanks x
