15weeks, worried over lack of appetite

In the first tri, I had bad nausea but I still had a pretty normal appetite. I took medicine prescribed from my doctor every night weeks 8 through week 13. Since the second tri, my appetite has been so low.

I’m concerned because my doctor already talked to me about how I shouldn’t be losing weight (I lost 5 pounds in the first tri). He told me I should gradually gain some weight and then gain more in the 3rd tri. I wasn’t worried about it because I’m not underweight or even close.

But now I have a lack of appetite. I have extra weight on me so I’m not concerned about myself but I am worried because I want to make sure I eat enough for baby to get nutrients.

I literally only have an appetite once a day, at lunch. I always eat a good sized, balanced lunch. By dinner time I feel starving but it’s so difficult to eat. I only want a few bites and still feel starving but it is seriously the biggest chore to eat. When I get like this, only carbs like plain pasta or potatoes sound like something I could eat a good portion of to get full but I know I need more nutrition than that. I usually stomach a few more bites of dinner and then quit.

I haven’t read anything about a lack of appetite in 2nd tri. Does anyone else experience this or have any recommendations?
