Weight gain

Hey everyone, I am just curious how much y’all have gain so far. I am 15+1 and have only gain 4 pounds, but 3 of those were from weeks 0-6 the other pound had been weeks 6-15(now) I think I might have gain some more weight but I have lost it again. I haven’t been nauseous in about a week but I still have no appetite. I might find something that sounds good to eat but I don’t eat nearly enough. Should I be worried? I did start my pregnancy out by being overweight at 5’8 and 190.
