I’m struggling to gain weight and it’s like ruining my transition😭

I (15mtf) literally don’t know why but over the past few months I’ve just been losing weight. I recently started estrogen in April and I noticed that I seemed to be getting more masculine which obviously I was upset and confused about. My hormones are where they should be but I was looking at older pics from like 10 months ago and I lost a pretty noticeable amount of weight. I don’t weigh myself so idk how much but now I look super skinny and it’s no wonder why I feel like I’m getting masculine. I’m losing all the fat in my face and now it’s just my bone structure. I guess could eat more but I’m never really hungry and it feels like I’m forcing myself. And tips to get in a lot of calories?😭
