Loosing weight and no appetite

Katy • FTM To beautiful boy

I am 17.4 weeks and I have been loosing weight so far this pregnancy. I did not gain anything the first trimester and so far I have lost five pounds in the second. Eating has been really hard. My appetite has massively decreased and when I do want to eat I get full very quickly. The baby is growing well so the doctor isn’t worried yet but it is still causing me a lot of anxiety. I worry I am not getting enough nutrients for the baby. I make sure I get carbs and protein at every meal and try to eat smaller meals more often as my doctor instructed. I do not have a scale at home but based on how my clothes are fitting I am either the same weight I was last visit or I have lost more. Has anyone else had this problem? Any suggestions on how to deal with this??
