I was TERRIFIED and I mean terrified of having one done!! I was even too scared to ring up. I procrastinated for years! Then I had DS went through many internals and stuff during labour etc so kinda lost my dignity(it did come back though!), and when he was 4 months old I suddenly thought, no I HAVE to go and have this done, for his sake, and mine of course.
So I called up, felt sick doing it, but better once Id made the call. I booked it for as soon as possible and went in at 8.30am(I felt sick and was beside myself with nerves), got it done and it totally wasnt as bad as I thought! It did hurt, because I wasnt relaxing, but I have issues with that during BD too

it took like 30 seconds maybe! and that was it!
It came back normal, and I had my second one when DD was 5 months, now I dont have to have another for 3 years :)
When you have your first one ever you need the next a year later, and if thats all good then no more for 3 years.
Go and book it hun, its soo important, and for like 1 mins discomfort that could save your life, why not do it
Also, they are very discreet, my nurse gets me to lie on my side and I have a sheet over me, and she only lifts it enough to do the smear so you dont feel all exposed and stuff!
