Don't worry Gracie, 23kg's and counting and i'm a couple of weeks behind you! i spoke to my ob about it and he said "Why are you weighing yourself?" He told me as long as i was healthy eating well and bub was growing, that i shouldn't even let it cross my mind. So i try not to, but i do hope they "fall off" as everyone assures me they will!
I was very active pre-preg, loads of surfing, hiking, running as well as a physical job, so to go back to just yoga and walking i guess i should expect to pack on a bit!
Everyone is so different. I looked about 30 weeks preg at 20 weeks, everyone commented, but now i am not as big as some other girls the same distance along.
So as long as you eat a healthy balanced diet, i don't think it matters liddlepixie, enjoy your new curves!
