Have I gained too much weight???

So when I first found out I was pregnant every one told me I needed to go to my primary doctor to confirm and at that appointment I was 125 from that appointment to my first idk two appointments I was between 117-122 now at almost 23 weeks I weigh 136 and am worried I’m gaining weight to fast I’ve always been a small person and just don’t want to over due it, I obviously know I’m going to gain weight and need to... I’m growing a human inside me lol. I just don’t want to gain too much weight, unnecessary weight.
