Weight concern

Hello mummies, before pregnancy, i lost about 20 to 30kg because I wanted to look good myself, was about 90kg. N first tri i didnt know I am pregnant and was upset i gain weight even though im not eating much but on 2nd tri i gain 15 kg. N constantly hungry. I scared i gain too much and not good. Will you all start to lose weight somehow? I eat in moderation and still gaining alot. I can gain 2 kg within a week! :(
