Weight 😢

I hope there is others like me

I've ALWAYS been UNDERWEIGHT and I was 107.5 for the past 3 days (record) and I lost basically all the weight I gained I'm in second trimester, I feel terrible because I don't want my baby unhealthy or worse but the weight won't stay on, I gained 21 pounds I was almost there for perfect underweight pregnancy weight until I Can have a normal weight ( in which I've never had) I eat and eat until I cant anymore (I eat more than my husband who is 190) I'm starting to feel like I'm never going to be healthy I've had this problem all my life and I can't change it i just want to be healthy and have a healthy baby I was only 7 away 😭😭🙏🙍😔
