Losing Weight end of 1st Trimester

So I went to my OB appointment and I’m down 10 pounds from the first one tomorrow I will have completed 12 weeks and entering week 13. I have had nausea BUT have not thrown up. I eat regularly because if I don’t I get nauseous. Doctor didn’t seem to concerned but said that she was going to take note to monitor this, baby looked healthy as well.

Today I also saw my mom after a week and she said you’ve lost weight. I’m a bigger girl but not huge, she is noticing the weight loss as well. Has anyone else lost instead of gained? I don’t want to be huge but I also want to be as healthy as I can.
