I’m unable to conceive. Is there a certain path or shabad to read to help my stress?

There is no specific Path for any specific disease.
However, stress and all sorts of mental problems can be overcome by studying, understanding and following Gurbani written in Guru Granth Sahib.
ਦੂਖ ਰੋਗ ਸੰਤਾਪ ਉਤਰੇ ਸੁਣੀ ਸਚੀ ਬਾਣੀ ॥ – 922
We need to systematically study and follow Gurbani. This will help us to improve our physical and mental health.
