No weight gain first trimester?

Anyone else not gain any weight during their first trimester? I’m 12 weeks today saw my on yesterday and my weight hasn’t changed. Im eating but just barely making it to 3 meals a day. Not sure if it’s normal or it’s the pre existing GI issues I had before pregnancy although since becoming pregnant I’m able to eat where as before I wasn’t eating at all. I did drop a lot of weight and was hoping this pregnancy would help me feel healthy again.
