Scared

So my husband an I have been trying for 5 years to get pregnant. Still nothing. I was diagnosed with cervical cancer when I was 21. But that has been takin care of. So thankful it was cought in time. But now the doctors are leaning toward my husband as to the one who may be the problem. We are going for a sperm analysis. An we both are very nervous.  Any help on lowering both our stress levels
