I am always happy to tell in case it saves some one's life!
I missed a smear which was my own idiotic choice, although I had listened to my stupid mother, who believed "everybody has pre-cancerous cells on their cervix, it's doctors poking about up there which causes them to change"
incidentally, don't see her now....
so, anyway, one night in october 2009 I went for a wee, and when I wiped, there was a watery pink discharge. Very similar to the start of a period. However, I am (was) regular as clockwork, and this was out of season discharge....
I was having a 'fling' at the time, and although we'd been using blobs, I freaked out that I had caught something 
I went to get a full sexual health check-up, thinking, sod mother, I'll keep it secret.
when the nurse did the pokey stick swabs, I bled a little. Very strange to me, but she said it was probably just chlamydia, and wait and see.
Naturally, I rushed straight over to 'fling's' house, and informed him he'd given me chlamydia (we had actually just called quits on our fling, but remained on fine terms)
However a few days later, my sex health came back all clear. I queried this, re the bleeding on the phone, but they told me to hang on as I was still waiting for smear results. I think at this point I had an inkling.
I remember getting a phone call the following monday morning. I was in the bath, and dts1 answered it for me. When he said, 'it's the doctors' my heart stopped in my chest.
I couldn't get any info over the phone, they just asked me to come in at half ten that morning. longest three hours of my life!!
when I sat down, the gp had a trainee gp with her. I could tell by poor trainees face something serious was up. She backpeddaled a bit, then jumped right in and told me I had cancer!!!!
have since found out that was not the best way to hear it, but what the hey!!!
I was treated amazingly, as lucky enough to live near RVI - top fanjo cancer hospital. I had a series of colposcopies, and some really awful loop excisions (shudders at memory) sadly, they didn't work, as each time they foung more cells. And in Feb 2010, they whipped the lot out.......
