Since I was pregnant 8 years ago an got old I been more.. obsessed with not gaining weight. I know the older u get it does get harder to lose. Well sept 4th I had a doctor appt.. since then I gained 4 pounds. I feel like i'm gaining it too fast. I am 9weeks pregnant

I'm sitting here at work crying cause I feel like i'm gaining too fast and i'm not use to it at all. I'm only 4'11 and I gained already like 8 to 9 pounds since getting pregnant. I looked it up an I should only gain 1 to 5 the first trimester. Besides walking what other type of exercises can I do while pregnant
