Nervous first time mommy help

I havent had any symptoms (besides cramping and being tired in the beginning) so i have nothing to go off of if things change. Im 16 weeks 3 days; i havent felt any movement in the slightest, my stomach is not getting bigger even my bf mentioned it wasnt.(i do have a baby bump but hasnt grown recently) i havent been hungry at all lately and when i do eat its small and when i force myself to eat i spit it out because i cant take anymore.

Is this how the second trimester is suppose to be? Im scared somethings wrong, eventhough i havent had any bleeding or severe cramping. Just hope one of you can put my mind at ease till my next dr appointment sept 7th.

I do have a muscle detatchment disorder, which makes it easy to bruise and not really well in the blood flow department. Dr should be getting my files by now.
