30 weeks and weight gain

Cinthia • Lost my sweet baby at 36 weeks. I love you Naomi. Forever and ever, you`ll always be my first perfect baby girl. :(
I was doing so good! I barely gained any weight during my first two trimesters but I'm at 30 weeks now and I gained like 10 pounds. I'm ready sad about it because I know it's going to be hard for me to lose later on. I didn't change the way I ate or how much my entire pregnancy so I don't know what happened is it normal? 😔 other than that I'm super excited about making it this far! 9 more weeks for my baby girl to be here 😔
