Increased appetite??

So according to my dating scan I’m 21 weeks, according to my anatomy scan I’m 23 weeks..haven’t talked to my doctor yet to see if he plans to change my due date. But my question is: is not having an increased appetite normal?? I eat my normal 3 meals a day with a snack at night…I have gained weight…also haven’t had cravings really except for a specific sandwich and green bean casserole…but when I “crave” those things I don’t necessarily feel like I HAVE to have them..it just kind of pops in my head like “oh that would be good right now”

Sorry if that was long..just trying to see if this is normal..
