Is it normal?

Agne

I’m 10 weeks pregnant and have had occasional nausea and severe tiredness but no other major symptoms. I’m quite slim and already been referred to specialist to keep an eye on me due to my low bmi. I’ve lost around 2.5kg with no sickness whatsoever, and that’s a lot for me! I don’t even loose that much when I’m really ill and don’t eat. Should I worry? I only get to see my midwife in March...
