Hey girls!
  Today I am 8w 1day, I am quite skeptical on my weight gain. It's constantly changing from 130.5 to 131.5 and I only weight myself weekly or twice a week. Does this seem to low? I feel as I I should weight more and if anything I shouldn't be losing that pound. I'm also only weighing myself in the mornings so it's not a daily fluctuation.
