Pcos and keto diet

I have done 4 rounds of <a href="https://glowing.com/glow-fertility-program">IUI</a> unsuccessful am taking a break before doing my first <a href="https://glowing.com/glow-fertility-program">IVF</a> but during that time I want to change my lifestyle I have PCOS but I am slim only weighing 120 pounds thinking about doing keto? I have heard a lot of women doing keto to help with infertility but wonder if I should do it since am slim and it helps to lose weight too. Any suggestions?
