opinions?

ok so i am.currently 14+2 and I started the pregnancy at about 232lbs doctor said I was healthy and to aim for about 10-15lbs of weight gain by the end of the pregnancy (as I'm very active and have had no morning sickness whatsoever so far with this pregnancy) well at my last appointment on Tuesday I had lost a pound. he wasn't to concerned and just said he expected me to.start gaining here soon (at least 2 pounds by the next appt in august) but I weighed myself today and have lost an additional 3 pounds. and I'm just wanting to see if its normal. if any other expecting mommies have had this? or any other opinions or advice you may have. thanks in advance!
