Advice needed on weight loss during pregnancy

Hi ladies i'd like to know if anyone has been in a similar situation or may have any advice for me? I gave birth too our first child 14 weeks ago, during that pregnancy i went from 68kg to 90kg! I began a weightloss regime 7 weeks after having our baby girl but so far im only down to 86kg. Heres the big news..im pregnant again! As selfish as this may sound im super scared about gaining even more weight 😣 Is it possible too loose about 10 to 15kg healthily through diet and excersise when pregnant as i know im going to gain some sort of weight throughout the 40 weeks.. Thanks in advance!!
