Meal replacement shakes safe for pregnancy?


Hi everyone. I’m currently TTC after experiencing a miscarriage back in December.

I currently drink meal replacement shakes (have been for about 2 yeas) because my nutritionist informed that I don’t eat enough calories in a day due to a sensitive stomach. Are they safe for pregnancy? Is there certain ingredients I should be looking out for? Like I said, this is so I eat ENOUGH not to diet or lose weight.

Thanks for any insight!
