Thanks so much Liz, I knew you'd be fabulous!!
I have seen your other comments on my other post but for ease will reply to both on here.
I will print off the links you supplied and go back to my GP armed with this information!
As for blood pressure, I don't know what machine he used last night. Doc gave me one to use at home (this was is Omron 711 ???). I have done a couple of readings last night and throughout today, my lowest was 116/93 but my highest was 139/100. My intentions are to take another reading this afternoon and then go back to my surgery today with all of the info you supplied and see what the Doctor says.
I think it will just be best if they refer me straight to hospital and take it from there. Our surgery is notoriously useless at prescribing anything, I agree it's all down to cost on their part. Unfortunately for them I don't care about costs, I think a bit of extra treatment for a few months in my lifetime isn't too much to ask - for any mum to be!
Thanks again, you're a real help.
