Feeling too small

Minako
I feel differently than my other pregnancies . I'm 26 weeks, but not as big as my other pregnancies. I have lost almost 4lbs This month. I never lost my previous pregnancy wright so I was over weight anyways, but I have gained 7lbs. Then today I fin out in the last month I'm down almost 4lbs from last month. I feel tired and hemorrhoids got me feeling bad. I have no appetite hardly the past week or so. My doctor thinks I'm just anxious. Tells me to rest, am I paranoid? I feel her kicking me tons and moving, but I don't have energy(I do take prescription vitamin D). I went and checked my BP and it was 134/83 a little high my heart rate was 112. Maybe just anxiety? I don't know. Maybe I'm getting sick? My nose has been stuffy a bit. Maybe I'm over worrying about it all. Baby measured on time, but here's a pic of my side view. Maybe it's bc Im having my first girl?
