She probably has early mild dysplasia, which is nothing to really worry about. It becomes worrisome if it develops into high-grade dysplasia, which is precanerous and often caused by HPV. This isn't always the cause though, sometimes it just happens. Did they do a biopsy for HPV or are they going to wait until after the birth? Also, there is a tremendous variation between labs on how many Pap smears come back and with what reading. Some labs will be very liberal in calling normal variations "atypical," which causes women to worry needlessly. Other labs have stricter criteria for this classification. It's probably nothing to worry about if it's low-grade. I have often done charts on patients who have an abnoraml Pap and the next one comes back with perfectly normal results. I wouldn't worry unless they tell you it's high-grade.
