Natural IVF

Gemma
Hello!
After 3 years TTC and 2 surgeries due to my endometriosis our doctor recommended <a href="https://glowing.com/glow-fertility-program">IVF</a>. 
I'm very concerned about all the drugs etc, so I found a clinic that does Natural <a href="https://glowing.com/glow-fertility-program">IVF</a>. 
After first consultation with all explanations from the doctor I'm not sure if we should go for mild <a href="https://glowing.com/glow-fertility-program">IVF</a> or just natural one. 
Anyone has tried this method? Any advice?
Thanks!!!
