A little upset about weight gain.

Mesha • Hubby and I have been together 8 years. Have a 2 year old boy and due in June with baby girl!
So I was quite overweight when I had my first kid and was worried I wouldn't be an active mom with him because of it so I worked my butt off and lost about 70 pounds and have maintained that for about a year. Now I'm pregnant again and have already gained 6 pounds and I'm 7 weeks. It makes me sad!
Don't get me wrong, I eat right and don't plan to starve myself or try to not gain weight. I'll gain whatever I need to for a healthy munchkin. But still part of me feels sad seeing that scale creep up. Anyone else experience that?
