I'm going to ask my mw about this on monday but just wondered if anyone else had this happen... My WBC in april measured 8.22. The normal range is 4-11. I noticed yesterday that my august result was 13.46. Seems like a big increase. I'm not aware of having infection at the time. Is it common to rise in pregnancy? Anyway i intend to speak to mw and ask if it can be retested to ease my mind.
