Welcome to HCM
Read your prob, this is matter of worry that you reduse 3kg weight during first 3month. as you mentioned you had spotting in first month for 2days may be this is sign of threatened abortion
. may be this is the cause of your reduced weight. so consult your doc get CBC n sonography
for fetal well being. if every thing will be normal then start high protine n carbohydrate
n calcium riched diet. during pregnancy
normally 12kg weight must increased.
