Thankyou all so much for your replies, i feel much better now! Even though i didn't exercise yesterday or today because its been so HOT! I'm not pregnant, so it must be water retention. I suspect some of it is muscle too, my calves are firm and not jiggly anymore, go me!

I don't think its because of the BFing, i have LOTS of fat stores to use up before my body gets worried lol. I want to lose about 25kgs and even if I do that, I still won't be thin lol, but my goal isn't thinness, its normalness - I just want my body to be how its meant to be and if I live healthily, my body should catch up with my lifestyle eventually!

Thanks for your replies everyone! *hugs*
