Amantilia, this is a horrible stage to be at, whether we're naturally slender or carrying extra weight, because there is no big obvious beautiful bump to wear with pride... and if you're still waiting to tell the world about it.
I was a BIG girl, and through hard work lost just over 3stone in weight, and was the smallest I'd ever been as an adult, so when I fell pregnant with Sophie, to feel my waistline filling out, it was really hard to handle, until the bump appeared. I never got back down to my lightest weight, so this time really do feel like I'm going to end up back where I very first started which is depressing to say the least, but then I also am trying to tell myself pretty much what Campn has said, this body is doing something AMAZING at the moment, go with it, let it all hang out - I'll deal with the weight once baby is here.
