Loosing weight/no reason

LovinMommy3310

I am 11 weeks pregnant. This is my second pregnancy, my next apt is not until the 18th of this month. Went I went for my first apt. they I had already lost 3 pounds during the first 8 weeks. I have now lost 3 more pounds; I do not have morning sickness, I have been eating like a pig (I must add that I'm a healthy eater but this pregnancy has forced me to eat junk food) I do exercise but less intense than before. I would think A) I would maintain or I would gain weight, Not lose it.

 I also have abdominal pain, this occurs pretty much through out the day. Since this is my second pregnancy I wasn't sure if it was normal.

I'm not expecting a doctors diagnosis but just some personal experience's. Has anyone else experienced this? Thanks!
