Struggling to keep glucose level in check

Did this first time yesterday.

1 hr after dinner the value came out to be 159. And surprisingly i ate half of what i usually eat in dinner.

I feel like i’ll have to starve myself for the rest of the pregnancy to keep with the sugar level. It gets trickier for me because i am vegetarian.

Or maybe i will have to take insulin shots that i am totally scared of.

I am also scared of getting a c section in case things get out of hands :(

Today, my fasting one was 103. I just drank 1/2 a cup of milk last night before sleeping after dinner
