My first pregnancy, was before I was diagnosed with diabetes, I lost my twins at 5 months not easy, as nobody could say 'why' as such, I say as such because they had a theory that it was something to do with a tilt! It was a very traumatic time as I know they were identical, and I'm an non-identical twin myself...
I had my oldest daughter with no problems until I hit the labour ward, but nothing major though.
My diabetic conformation was given to me, in the same phone call that confirmed that I was pregnant with my son, double whamy as I wasn't expecting either at the time, that was 23 years ago under the old carb exchange system a lot stricter diabetic regime than today's, so spent 3 weeks in hospital starting my insulin regime..
9 months later, I fell pregnant with my youngest daughter, and she was fine as well.
Said youngest daughter is 37+2, so I'm going to be a grandma any day soon :shock:
Sadly since having my youngest daughter, I have suffered 5 early miscarriages, but these weren't diabetic related, but to do with the tilt that they felt caused the lose of the twins.
What you need to do, is asked to be referred to your 'diabetic pre-pregnancy clinic' this is a specialist clinic with higher and specialist input to prepare you for pregnancy, giving all the information concerning the risk factors for a diabetic mum, helping you bring your diabetic control into a suitable range that gives you the best chance of going through the pregnancy with minimum of problems etc..
Good luck, I'm sure that everything will work out fine...
