Worried about intake and baby growth

I’m currently 22 weeks five days, I gained 12 pounds since my pre-pregnancy weight and I’m currently trying to eat 1700 cal as my doctor recommended in the first trimester after gaining around 8 pounds during that. Since then I’ve had days where I’ve eaten between that and 3000 cal based on my cravings and have listened to my body but since my anatomy scan my babies’s present is 19th. I know technically that’s still considered within the normal range but I’m worrying that I’m not eating enough and everyone wanted me is mentioning that 1700 is not nearly enough. I feel good eating that and I’m just prioritizing healthy food rather than junk food, but should I be worried that I’m not eating enough my first OB appointment is next week March 12 so I will be discussing all of this with my OB but wanted to get some advice or opinions on this.
