Weight gain

So I had my 32week check up today saw I gained 9lbs from 28 weeks to 32 weeks my husband was on vacation so we indulged in eating out that's what we do on vacation. My OB doc wasn't to concerned I haven't gained 30lbs, yet that is lol I still have 8 weeks to go but, she told me to keep an eye on my portions. I'm pretty active and do some light weight lifting,

this is my 2nd pregnancy I don't know if I'm over thinking this or not. I gained exactly 30lbs w/my first pregnancy
