Help! Husband is diabetic? Anyone with the same problem?

Kaitlyn • Mom of one beautiful daughter ❤️ Ttc baby #2

So at my obgyn appointment all of the test came back normal. We have been ttc for 7 months. I meantioned to my on that my husband is type 2 diabetic. She said that him being diabetic could be the reason why we are having a difficult time getting pregnant. Has anyone else had this problem and if so have you gotten pregnant and what did you do to help getting pregnant?
