Please help TTC

Brandi.
I am now 30 years old. However, when I was six years old I had a form of cancer. I was treated with extensive and crucial chemotherapy that left me and fertile. I had an HSG done in 2010.The results of that test concluded that both of my tubes are blocked due to scar tissue or damage from the chemotherapy. My husband and I did <a href="https://glowing.com/glow-fertility-program">IVF</a>, and it worked the first time. We now have a three-year-old little girl. My insurance will not cover <a href="https://glowing.com/glow-fertility-program">IVF</a> again.we would love to have another child. We never use any form of birth control is there anything naturally that I can do to try to unblock my tubes? Any help is appreciated thank
