My What to Expect When You're Expecting book says that in the 1st trimester the average weight gain is 0.9-1.3kg.
OMG! 1.3kg! i guess i better ease off on my MS eat-what-you-like diet.

how long have you been at pilates for? I was told by a midwife that runs prenatal yoga that you can't do any excercise at all (only the walks and swimming) until 12 weeks! so i quit my pilates and strength training to try and be good? but i'd love to start back at pilates?
