When should I worry about weight loss?

Morgan

I am 7 weeks pregnant. A week and a half ago I weighed 132 pounds. Today I weigh 122 pounds. I have lost 10 pounds in under 2 weeks! I know it's normal to lose weight in the first trimester but 10 pounds seems like a lot to me! I'll ask my OB but my next appt isn't until the 19th :(

My appetite has decreased but I have managed to eat small meals throughout the day (mainly fruit).
