I just got back from my 16 week appt and I am up 15 lbs :)
This is my usual m.o.
I always gain way more than others in the 1st tri. I usually gain between 35-40 in the end. I always have been able to lose it all within 6 mo without even working out. Just by breastfeeding and watching portions and such... And running after my other kids, I guess....
Don't worry about it. I mean, I would keep an eye on myself - obviously you would prefer to avoid another 11lb in one-mo gain if possible.. But our bodies largely do what they need to do IMO. You get to make the choices of what goes in, but you can't control the hunger and the hunger deserves to be responded to.
