Weight loss

Nooshka • 9/6/15 💙
I just weighed myself for the first time since my original midwife appointment at 6 weeks (now 19 weeks) and I've lost two stone.
I did spent about  8 weeks being sick every evening but should I be worried? We have an appointment next week so I can bring it up then but I'm starting to worry. Can anyone set my mind at rest?
