As long as your Dr is not concerned don't worry. With my first pregnancy I gained 63 pounds, 2nd gained 20lbs, and my third I gained 4lbs. All of my babies were healthy.
Lucky u! I'm 25 weeks and I've gained 18
Agreed^ your doc would tell you if you need to gain/lose weight
As long as you and your baby is healthy then yes. Every body is different.
