Gestational diabetes

Tracey • little girl Ivy🌷❤ kaleb💙💙
So I've been diagnosed with diabetes but my blood sugar allowed me to still eat as I pleased but as the weeks go by my hormones increase causing me to produce less insulin and now my sugar is getting higher every week. What do I have to keep it under an hour after a meal ? Its been close to 7.8 almost every meal. And do any of you know a good meal plan website!? Thanks!
