Welcome

I'm presuming your partner has been checked too? Obvious question, but best to check
If your BS is under control, then that's a major thing so you've made a good start
Have you tried a fertility app or ovulation tests? There's a surprisingly small window when you're fertile.
Have your doctors given you any advice at all? Have you had all the tests or just a few?
Difficulty conceiving is surprisingly common. Around 1 in 6 couples have some difficulties. But remember, most are sorted
My advice, if you and your partner have had all the appropriate tests, is to keep up the good work with your blood sugar, eat a healthy diet with plenty of veg, healthy carbs, protein and fats (fats are important for fertility), track your ovulation, and perhaps try some kind of relaxation each day. Even sitting quietly for 5 minutes a day and doing some deep breathing can help relaxation.
Final tip - focus on the things above. Don't focus on conceiving, if that makes sense? That's what people mean when they say "Try not to think about it and it'll happen".
