Advice! #2 Pregnancy

Pumpkin • Girl Momma 💖 Baby Girl #4 due in Oct.

I'm currently pregnant with my #2 baby and this pregnancy as been a total opposite of my first one. So I was wondering if anybody else wasn't gaining much weight the second time around? I'm also wondering if I could be carrying a girl and this pregnancy still be a total opposite or if it could possibly be a boy this time around because of such a drastic change?
