N2L, it's funny, but I actually lost weight while I was pg with DD. On the morning she was born (before she was born), I weighed 13kg less than EPU day. Take out the baby, amniotic fluid and placenta and my OB said I'd just lost 7kg, so I was 20kg less than EPU day at the end of the day she was born. Of course, my FS assumed I had gained weight while pg, so it was fun to correct him. Just a pity I have gained most of it back. I lost weight while I was pg last time too. I think being pg gives my metabolism a much-needed boost... My TTC journey is full of Catch-22s - pg is great for treating endo but I need the endo treated to get pg; pg makes me lose weight but losing weight will (maybe) help me get pg... *sigh*
