For those who are or were over weight?

Hi guys! So im pretty much obese bmi is 32, testo levels are slightly raised. Height is 168cm And weight is 91kg (200pounds) 
So my question is ive been trying for over a year and we assume its my testo levels thats stopping us since it's the only abnormal thing which is from weight related. How much weight did yous lose that you ended up falling pregnant!?
Your advice and tip will help me alot, please share your stories.
