Jacks, hope you are starting to feel human again. Its horrible. More 
for you and rest as much as you can.
Smellysocks I hate to say it but yes a gynae will need to use a speculum. And they will have a good old poke about and ask you where it hurts bloody everywhere and where it doesn't. BUT they should use a numbing gel thing beforehand, to make it not as bad. I wont lie, its unpleasant and afterwards you will feel like someone has kicked you but a couple of paracetamol and a bottle glass of wine (I had my last appointment after 4pm so it was wine time when I got home). It was also good that I took my DH with me for the appointment as it was the first time he really understood just how uncomfortable and unpleasant things can be at times.
Also, the main thing to remember is TIME. You will hear this a lot but time is a good healer, every week and then month that passes things get slightly better/more bearable.
I had an overdue smear test done at the colposcopy unit 16 weeks after giving birth and I was in tears, more with the fear of the position I was in, which was almost identical as I was in when delivering (I had PTSD and PND kicking in around the same time). The ladies there were very very understanding and held my hand, made me a cuppa afterwards and made sure I was ok before going home. However, I coped and the actual physical discomfort was alright. You did hypnobirthing so you could use some of the same relaxation or breathing techniques. And just tell them beforehand your concerns or worries, they will not laugh at you or make you feel silly.
Bit of a long post. Struggling a bit these days so it helps to write stuff down and if it helps anyone in a similar position then great. And thanks for reading.
