First consult some infertility specialist for what type of treatment you need.As you are married for 7 years plus
diabetes plus 34 yrs of age you might need ivf..ivf needs couple commitment, time,money and strength.so please before enrolling for ivf talk to her. Ivf needs rest for min 15 days post embryo transfer.
Second option if she doesn't want to take break from her job you can opt for surrogacy but that would cost you a lot.
So my advise would be to counsel your wife and take appropriate treatment before she turns 35 yrs.
