Cancer Survivor TTC

Last year at 27 I was dignosed with sarcoma. I had surgery in May 2014 to remove the tumor. Did <a href="https://glowing.com/glow-fertility-program">IVF</a> treatment in August 2014 to preserve my eggs in case the radation treatment caused infertility. I had 36 radation treatments. In the last 2 months my cycle has started to regulate. My husband and I have decided to TTC. I'm wondering how long should we try before we decide to use my eggs.
