Hi I am 34 years old. I was diagnosed with breast cancer 3yrs ago, I underwent all medical treatment from chemo, radiology and surgery, one breast mastectomy. I know the doctor said these treatment may cause infertility and I may not be able to be pregnant after. was put on daily pills for like 2yrs as the doctor said before trying to get pregnant. my ovulation is back and have been trying for more than 6 months now but nothing. Is there a possibility still?
