Is this normal ?

So I don’t have a healthy appetite, I’m 17 weeks and I get full soo fast. Like I can take about 5 bites of something and be full. I had HG in my first trimester and i was constantly throwing up, couldn’t keep anything down so I lost a lot of weight. Before pregnancy I was 144 lbs now I’m 128 but my nausea subsided about two weeks ago entering the second trimester, so I can eat now but I don’t eat much at all, I eat like twice a day and I feel okay but it’s normally after 4pm whenever I feel like I should eat. I wonder is this normal? I want the baby to get all the nutrients she needs. I also take my prenatals cause i know I don’t eat regularly.
