Eating too much sweets/chocolates

I’m currently 13 weeks plus 4 days and studying for my exam (post grad.) and craving chocolates and started eating them almost daily.

And now suddenly I felt guilty and concerned

Am I increasing my risk of getting gestational diabetes?

I’m 32 years old

My BMI prior pregnancy was 30 I wan on steroid for chronic allergies

And I don’t have PCOS or a positive family history of diabetes

So do you you think I have a high chance? And I should limit the sweets intake?
