Worried

I’m 14+3 and since finding out I’m pregnant I have lost over half a stone (about 3.5kg).

I’ve been struggling to eat, throwing up and having a few emotional issues which are also contributing to that (I am trying so hard for the baby but it’s so difficult).

Is this weight loss something I should be worried about? I’ve got an appointment soon with my midwife so I will bring this up to them but I wanted to see if anyone else has had weight loss during their pregnancy and how much you’ve lost?
