I just had one about 2 mths ago. Before I was pregnant with Izzy I hadn't had one for 7 years *slaps wrist hard* and when I finally did go I had stage 2 and 3 abnormal cells and had to have a biopsy and heat treatment for it and now I have to have very frequent, regular pap smears. Please ladies if you are overdue - go pick up the phone right now and book in. I will never let myself go so far over with appointments because it was really scary and not pleasant having the treatment.
