Losing weight in first trimester?

Nicole • Forever missing my angel baby 👼🏻❤️ my rainbow baby girl Juliet was born March 15, 2019! 💗🌈

Ladies is this normal??

I have had nausea and no vomiting this whole pregnancy , the nausea wasn’t enough to where I was barely eating throughout the day

I’m 12 weeks 4 days I haven’t weighed myself today but last time I did I was 4-5 pounds lighter than I was when I got pregnant.

Is this ok? I HAVE been drinking water everyday nearly all day and before pregnancy I did not so maybe that’s why??
