Hi Lizzer, spookily enough on our similar path of life (!!!), yep been there. Pre-children, just after we had married, so I was like you, thinking, I'm too young, I've just got married. In a new job so didnt really know anyone there, pretended I was having day off to go shopping etc, horrible horrible time.
But anyway, it is not horrendous, honestly.
Think positively, you've had a baby, you've had smears, you wont be anxious and nervous of things going on down there like many women are - which really adds to it.
I had a lady Dr and a very nice nurse who held my hand, as I wasnt a very brave girl at all!! As I didnt really know what it was all about or what was going to happen, hubby was outside and I was on my own, looking back I wish I'd had someone else with the nurse to hold my hand - your mum perhaps?
Dr had a good look, similar instruments etc to smear. Then a local anaesthetic 'up there', probably my worst moment as I had a needle phobia (which since kids and blood tests I no longer have) they cut out the yukky bit there and then(some do lasers etc). And showed it to me in the jam jar afterwards! They put a dye to show up the bad bits.
Bit like a period afterwards, tiny bit of blood (nothing like post baby) and honestly that was it.
You are then put on regular smears and checks, which makes you feel much safer and looked after, I think it was after my 3rd it showed abnormal again, so I had another colposcopy and all was OK. Which I found reassuring.
So all in all, dont PANIC, they are PRE PRE PRE cancerous, they are there to get them in time, you will be fine. Lots of love xx
