I am 66 years old. I was put on a Z-PAK for congestion at the same time I also got a flu and 5 year pneumonia shot. 3 days later I had some spotting. I have been back for a pap and I got a letter saying that my smear showed abnormal. Could anything that I had have caused the spotting since I haven't ever had a problem before or could any of those shots cause an abnormal reading?
