I lost 2kls in 2 months since the quarantine started

Hello po mga mommies, I would like to ask lang, is it normal that I lost 2 kls when I'm 22 weeks pregnant already? The first weight I had recorded was 68.5 kls, I was only 2 months pregnant then and now I'm only weighing 66 kls. I started eating less rice coz the elders told me to eat less of that to avoid getting "manas" and to help prevent having problems when giving birth. Thank you for answering! God bless everyone. ?
