Conceiving after cancer.

Meagan
I have been trying to conceive for a year with my husband with no luck. When I was 13 I was diagnosed with thyroid cancer. I underwent surgery to remove the goiter and lymph nodes. I also had several rounds of radiation treatment. I take synthroid everyday since I no longer have a thyroid. I'm just wondering if anyone else whose undergone treatment for cancer or who takes synyhroid daily had trouble conceiving afterwards?
