I feel really stupid. I have had fairly irregular periods since i had DD2 9 months ago.
I turned 25, 6 months ago when I received my smear test letter.
I don't know when to book it, should I book it while I'm on my period so I can tell the receptionist I have irregular periods so she will perhaps book it for the week after?
Or do they book well in advance? 
I've just come out of hospital for pneumonia and I was flagged up on the system for not having my smear test yet and it's given me a kick up the bum.
I've had 2 children and obviously had all sorts of tests down there but I'm so nervous
