I keep getting sent reminders to go for my smear test. The last twice I had one done the nurse said she was having difficulty reaching the neck of the cervix and I wasn't altogether convinced that she'd managed to take a proper sample. However, that's not really my question. I've been married for a very long time (happily married, I might add) and both my husband and I have only ever had sex with each other. Do you know if a smear test is really necessary? What can it tell me?
