Weight gain / loss

First pregnancy and I’m 20 weeks going on 21. During my first few weeks I lost a lot of weight cause I wasn’t eating at all but I’m not sure exactly how much because I didn’t weigh myself. I just got smaller. By week 13 my appetite did come back in full force but I haven’t gained any weight at all. I’m usually 119 pounds and right now I’m stuck between 116 and 117 past few weeks nothing more. I’ve been eating and craving full meals which I eat almost 4 -5 times a day with fruit but still nothing. From my previous ultrasounds the baby seems to be fine and moving a lot I’m just upset I’m not putting on what I want to. What did you guys to for weight gain ?? I feel like I’ve been losing more than actually gaining and I don’t want to look like those ants 🐜 that carry more than they can bare if u know what I mean .
