Welcome Allejane, sorry you have to join us here! Hopefully you will have as smooth a ride as possible with your GD & pregnancy.
I was pretty nervous about the finger *****s as well, but I'm kind of used to it now. After doing it daily for a month or so, I am now only testing 3 days a week, so if you can keep your levels under control things can get easier. I have found that I can even eat the occasional sweet thing. I found it a case of experimenting when I first got diagnosed. It was funny the things that would send me over - eg supposedly OK cereal and yoghurt, but then other things surprised me; can eat lots of pasta with no problem.
