Vin3 & pregnancy (pre cancer)

Taylor
So I'm 7 weeks pregnant (yay) 
I have a rare condition called VIN 3 and was wondering if any other mummies out there suffered the same, what your pregnancy was like etc etc
I am having an op early October as it can only be done past 14 weeks - worried about the effects of general anaesthetic on bubba? 
Also completely unrelated but I've been getting bad tummy ache the last couple of days...what could this be? X
