Personal Question - IVF & Weight

Michelle • TTC our first baby!!
So my FS has refused to start our IVF cycle till I loose 10kgs (25 pounds). For those women who have already undertaken an IVF cycle, did you put on weight, and if so what range did you put on? I know each woman reacts differently to the meds, but I am curious how it may effect me & if I should plan on loosing more in the timeframe. I appreciate any insight!!
