Gained 9 pounds in the last 3.5 week. Is this okay?

So I was around 146lbs to 148lbs pre pregnancy weight. I never gained any until about 21 weeks due to nausea and I weighed about 150lbs at my 21 week checkup. Now I'm 24w3d and I'm weighing 159. That's seems crazy fast to put on almost 10 pounds. That would be 3 pounds a week the last 3 weeks. I'm really worried about gaining to much this pregnancy. I'm just so hungry lately and I don't know whether it's healthier for the baby and I if I try to ignore my hunger and not eat or to just eat. I do indulge in my craving but not extensively. My meal portions are definitely bigger I must say. I'm just worried I'm gonna continue to put on weight so rapidly
