I have lost 6lbs from my pre-pregnancy weight. I lost 5lbs early on but then I stayed at that weight for a couple weeks. Then I went up 3.5 lbs but lost that as well. I have MS but it's not like I cannot keep anything down. I have only really thrown up 4-5 times. I just have a very small appetite. If I overeat, I get sick. I eat small meals and several snacks all day. Do you think it's concerning? Like I said, I am not throwing up so I thought I was ok until I weighed myself.
