weight issues

i just weighed myself.. 48kg..
before i was pregnant, i was 50kg
now it just keeps going down..
give me another month and i think i’ll be 47kg

it’s not that i’m not eating… in fact, i’m eating a lot including supper
blood test shows that nothing is wrong…
but why it justs keeps going down?
some might think it’s good, can’t tell i have a son..
but my bones are really showing, especially my chest and collar bones

according to my mum, my shoulders are starting to “collect rain water” ..
