NHS fertility wait time Scotland?

We have been referred for fertility treatment after trying for over a year, I have PCOS and my doctor said they may have an issue because my BMI is 32 and they might need me to get it lower. I already go to the gym 5 days a week and because I’m 4”11 I’m finding it difficult to get to the weight that’s considered ‘healthy’.
Anyone else had experiences like this or can let me know how long roughly you waited for next steps? I’m hoping we can still get referred successfully it’s been 2 months so far.
